| Post subject: ADSL China telecom slow connection to websites outside China |
My problem is 99% of the time I am using websites outside of China.
Like reading the newspaper in Europe and doing online trading.
The connection is SLOW and China Telecom can only guarantee the speed for websites in China.
In my last place I had a cable connection and no problems.
Does anyone have the some problem? What is the fastest connection for website use outside of China? |

It will be slower than usual because of the date. Extra monitoring of traffic takes more time, even for computers. The same thing happens at Commie Party meeting time. |

My guess is that this is not to due to monitoring (from one what I heard/read about how they monitor it is not inline or realtime for webpages) but because of congestion on one or more of the links, most often the transatlantic ones. Typically ceratiain sites are affected whiles others aren't - this is just because different sites use different routes. You can test this theory using a tool like tracert/traceroute for command line orientated users and pingplotter for those who are more comfortable working with GUIs.
For example, from the time I have had extreme latency probs with Ameritrade while Etrade has working just fine - and I would hardly consider Ameritrade a hotbed of counterrevoluntionary sentiment.
Give it time and it will generally resolve itself. There is little you can do (although sometimes using a non-Chinese proxy allows yuo to exploit less congested routes and improves perforance). |

Thx for your respons. I have done a trace and shown this to the guys from China Telecom which came to my app.
Most of them don't know whay they are looking at all they say it is out off there hands.
Most of the the times it goes wrong in the US were they use SPRINTLINK.NET and then you get 700ms time jumps.
Each tjump is about 700ms and with about 15 step before you are there it takes a long time.
Again before I was using cable and everything was fine.
I am just hoping to get some advise in whcih cable or DSL does work quick. |

Logic dictates that there must be people at China Telecom who at least have some clue about networking technologies, my experience is that most of them would have problems locating the power switch on your average computer let alone remedy complex network problems. Make, are you comfortable with the concept of MTU? An incorrect MTU setting is often the culprit for strange connection behavior - you would see, for example, that some hosts work perfectly and others work intermittently if at all. What operating system are you using? I can try and track down the appropriate instructions if you are not confident locating them yourself using a search engine. Network performance - particularily network performance - appears to be cyclical. There have been periods of time when my bank has been so painfully slow to use that I never actually completed the login process before it timed out. Most of the time, though, it works like a charm.
To answer another question, generally performance to international sites is good-to-excellent, depending on exactly where the site is located and how the packets are routed. Latency is surprising good and throughput puts my previous @home cable modem (in MA) to shame. I pay for 2 Mbit/sec downloads and regularily get 200 kbit/sec plus on downloads. |

ADSL is not the fastest. Great wall broad band and FTTB+LAN are faster. But usually u can only get one broadband at one place. u can check it out anyway. |

From what I saw at CT, FTTB+LAN is limited to only 512 kbit/sec - what's the top speed you've seen? Is it from somebody other than CT? How about "Great Wall Broad Band"? Whose the provider? Residential ADSL is available up to 8 Mbit/sec.... I don't mean to imply any disbelief or disrepect, but it's so hard to get accurate information on what is and isn't available here until you've done it yourself, so I'd love any more details you can give. |

i just checked the expert. Theoretically FTTB could reach 100mbps and so is the Great Wall. But, usually it only applies to domestic websites. So when it comes to foreign website, ADSL is actually faster(not always). As a foreigner, u can apply T3 which is super fast broadband. But u need to register with your passport and get permission to use it. However, it is possible that with the same broadband in different areas there will be speed difference due to 2 reasons: either the width of broadband is dfferent or more users in one area. Just like traffic problems. |

And where is this "expert" getting the information from? We'd like to see links.
Indeed, the theoretically maximum speed of FTTB is limited by the last few hundred meters - in this case, an ethernet connection - which would typically be 10/100 mbps although most medium- to high-end machines sold today already support 1 gigabit networking. In practice, though, I can tell you that if you go to the China Telecom office on Cao Xi Bei Lu, you can ask and they will point to a fee schedule on the wall indicating that residential FTTB is in fact capped at 512 kbit/sec... same for the apartment complexs I've checked out. |

i forgot to mention we use FTTB+LAN at home and the indicator on my computer is 10mbps. It is pretty fast. The provider is shanghai telecom. It uses separate line from the telephone line. if u can read Chinese, check this webpage
http://www.cntele.com/telecom/fttb.asp
The network doesn't cover everywhere in Shanghai. Different residential areas have different broadband options. |

So that's just 10 Mbps ethernet and doesn't tell much about the connection from your building to the outside world (I see 100 Mbps to my ADSL modem  What's the maximum download bandwidth you've ever seen with your setup? |

Hi guys, I see there is some response. I don't know MTU settings. In run Windows XP pro English.
About speed: In China I can get 200 kb/s ( I have 2 MB connection )
But outside China it depends whcih routing they use. For some websites no problem it is just the ones I use the most which have these problems. Doing a trace ( Windows XP, so c:\tracert ) then U can see the connection slowing down at a server in LA (USA)
Sprintlink.net is the name. The problem is how to change the route which is used to get to the website you want??
I don't think I can do anything on my side, it has to be done by China Telecom. |

There are some routes that are much worse than others - although a 700ms latency means something is going seriously wrong. I would suggest you find and download pingplotter (google "download pingplotter") and use that to visualize the latency and packet loss at every hop. I do seem to recall seeing horrible performance from Sprint before.
In practice, you have no control over the routing of your packets. |

using proxy if possible to browse what you need or surfing avoid the peak time when the traffic is over jammed! |

Sure, pay more money, and give as little as possible to China Telecom (they'll squander it all on luxury cars for upper management and continue to allocate 0.0001% (+/- 0.005%) of their gross income to customer training. It my personal belief that their customer service unit is so poor they need some kind of basic government assistance grant, including necessities such a any kind of training whatsoever, a minimum level of familiarity with the telephony system, and so on and so on, because, based on extensive experience with their employees both in callcenters and in their service halls, they are unable to pay the medical bills necessary to treat the endemic, deeply painful and undoubtedly extremely embarassing condition that can be the only possible explanation for the uniformly sour and pained look on their faces/sound of their voices as they brush away/lie blantantly about/ignore customer complaints) - and (phew, that was long long parathetical expression, if you ever read this, Mrs. Wheatherby, my senior grade English teacher, remember that Shanghai is a long way from Illinois, and by the time you ever reach me I'll be long gone) get a point-to-point high speed connection from a US-provider. That way, although the customer serivces may be only impercetibly better, at least it will be an IDD call away and the long hold times combined with music designed by ex-CIA PsyOps to encourage customers to hang up at the earliest oppurtunity (it's a little known fact that companies adopting this approach save even more money on "customer service" than those that moved their call centers to India) will mean complaints are unlikely.
Oh, and if you are just downloading songs/movies from kazaa/iMesh (www.imesh.com) for "evaluation" purposes, don't let them sell you anything below an OC-24.
Okay, I'm going to bed now. |

LeiFeng,
yes....your opinion on our China Telecom is quite right... they squander it all on luxury cars(not will, it has already done... and will continuing....i think..)...
but the main reason outsite of china is so tardigrade..i think ...Internet is so unfair
in recent year, china just developed her IT science and technology, but the IP address assign to china is so exiguity..as you can see this almost not static IP address assign to personal client..go without saying the outside speed..
yes... Our ISP is getting behind , but it just time problem ...when the IPv6 is coming, i think there's no this kind of problem to puzzle you foreigner guys... as you can see , the economic development of china is fast...it will come soon..i believe...
LeiFeng,
how about your sleep.. do you have a good night?? i feel you are an evil just like many guys in the chatroom, never need any sleep... lol...
just joking..you are a hardworking and braveness guy...

This thread and many other show clearly…
CT intentionally cripples broadband technology they've got. Considering their multibillion-dollar technological purchases in recently years, I can’t help but feel that the primary purpose of their shiny Cisco firewall routers is to prevent their other machines from providing full services. What an irony!
Despite those obviously aggravating experiences for someone who are not used to this type of aggravating experiences, most of the Chinese users feel they are experiencing what was thought impossible a little while ago. They feel this way, and then hype even about the bandwidth. What a pity!
Don't tell me the $20 ADSL you’ve got is cheap, because it is not! How many ports you've got yours blocked? And how many times your hard disk got scanned a day? It is like....How do you want to be hacked today? Enjoy your day on the net  |

Ha, LeiFeng, I like your post. But weren't you the one who, months ago, was gushing about the wonderful speed of China Telecrap's ADSL...? I'm serious -- my dial-up is faster than my ADSL. This is the case at now two locations I've lived in Shanghai. Also, my AIM works fine with dial-up but not ADSL. |

The line isnt bad for doing P2P. I usually max out the speed my CT claims. It might be this, he was happy  |

| Post subject: China Telecom is very bad! |
From arround more than five week I have a problem with China Telecom I can't visit same website and also I have the same problem to download the email from the pop3 account. I ask to China Telecom and they tell me that they have a congestion problem but they also tell me that they don't know when hey solve this problem. When I trace the website I see that the problem start at the enter into router 202.97.33.90 and later continius into the bad US network sprintlink.net
I hope that China Telecom understand realy this problem as always the person that I contact tell me that this problem is out of they hand. Nobody tell the problem is my!!! Last two days I stay in Hangzhou and the ADSL connection from the Hotel was wanderfull.... I don't know why this person from China Telecom ask which routing they use in Hangzhou I explain to them but China Telecom is a big company but in every city will be a different company with the same name so the only way is find other way to surf the net. In any case if you surf the net from Shanghai from ADSL, ISP or the other net all arrive at the same routing and all have the same problem this is what the China Telecom Engineer explain to me the only way is hope that they upgrade the HW asap.
Regards
Deniman |

China Telecrap's 'corporate' structure reminds me of SBC PacBell in California -- a bunch of random departments who don't communicate with each other (sadly ironic for businesses that claim to facilitate communication). Trying to get one thing done is often a "catch 22" battle -- you can't get A done until B is set up, but you can't get B set up until A is done. This was the case during my recent home office move from a different district. The two district departments could only communicate with each other when involved in billing me. No surprise! |

| Post subject: China Telecom Employ not intelligent |
Today I call again China telecom because the problem still continius I make the tracert of a lot of site and I see tha the last Chinese ip is 202.101.63.254, later go to USA IP 202.97.33.90 and 202.97.51.206 and then to sprintlink.net . Today coming a stup... guy at my home and go to the site online.sh.cn and show that the download is fast! Is ridiculus as they work! I explain to him that this is no way to show that the network work! I show him the trace and also with Hotmail or yahoo the most bigger site in the world also it take more than 900ms to arrive to destination the trace but if you go out of Shanghai this work properly and I see that the last Ip before go outside from china isn't the same so China Telecom in Shanghai don't want understand that they must re route the traffic into other routing port because meabe the net that they are using have same problem that in the other cities of china they don't have. Also they tell that they have congestion problem ok, but if is true that they have congestion problem why they continius to sell this service?? Meabe they can reduce the band if they have congestion problem. I pay for a 2 Mb/s that can only be use for P2P but not to surfing the net google I don't see a lot of page, godaddy I can download the page or only ones a week, yahoo and msn the same not see or only same time.
If anybody can help to solve the problem is apreciated! |

I've posted about this before: Godaddy has a policy "no business with China, including Hong Kong". I have several websites hosted with them and I"m going thru hell trying to FTP these sites and move them to a reliable host. I also have trouble with other websites hosted with Godaddy, access from China is worse than 10% uptime. They tell me it's THEIR POLICY, not the fault of China gov or ISPs. They won't explain WHY they have this policy, but I think they SUCK.
Deniman, I'm having the same problem as you with my slow adsl connection. If you find out any fixes, please share!! |
