simon43 Posted June 12, 2022 Share Posted June 12, 2022 For about the past 4 days, I have had major disruption with my Zoom/Skype classes with students in mainland China. Their internet speed is fast, so is mine. But in the 'middle' is a problem..... I did a traceroute and the problem is clear - it is an unreachable router on the 3BB backbone. I emails 3BB technical support about this, but the words 'traceroute' are not in their dictionary....... Useless bunch. Any workaround? I tried to use a VPN via a server in Hong Kong, but no joy at all. Link to comment Share on other sites More sharing options...
Peterw42 Posted June 12, 2022 Share Posted June 12, 2022 If it still fails using a VPN via Hong Kong, wouldn't that prove the fault is outside Thailand ? Link to comment Share on other sites More sharing options...

The traceroute fails at an ip address that has a DNS name of xxx.3bb.co.th I have no idea of the routing between my location and the VPN server in HK - maybe it is a multiple location fault?

Mavideol Posted June 12, 2022 Share Posted June 12, 2022 (edited) usually to be sure all works smoothly with China it's better to use WECHAT Tencent/China CCP controlled but... that could be an option Skype is blocked in China and if I remember my kids friends had problems with Zoom as well Edited June 12, 2022 by Mavideol Link to comment Share on other sites More sharing options...

Do you mean the IP addy's is masked? This is where it enters 3BB switchgear, you aren't going to get an IP. You are talking to the wrong people at 3BB - Ask for a call back from the ISP team, they are awesome (actually its been the same guy for years), explain your issue and will solve your issue. FWIW I haven't had any issues with China this weekend, but others have been reporting issues. Edited June 12, 2022 by recom273 Link to comment Share on other sites More sharing options...
DrPhibes Posted June 12, 2022 Share Posted June 12, 2022 The Great Cyber Wall descending? China has been trying to stamp out "Outside Influences" and that effort is picking up steam. 1 Link to comment Share on other sites More sharing options...
fdsa Posted June 12, 2022 Share Posted June 12, 2022 try using a VPN server in Singapore. Link to comment Share on other sites More sharing options...
muratremix Posted June 13, 2022 Share Posted June 13, 2022 A singapore vpn may not help. China direct bandwidth is expensive. You may need a vpn with China direct bandwidth, and they are not cheap. Link to comment Share on other sites More sharing options...
simon43 Posted June 13, 2022 Author Share Posted June 13, 2022 Usually I have no problems getting into China using either Zhumu or Zoom. This is a routing issue with 3BB (at least that is what my traceroute suggests). I will try using my AIS mobile data to see if that gets around the problem. (Actually the frustration of interrupted online classes encourages me to go back to in-class teaching, after 4 years of online teaching and away from the classroom. Unfortunately, if I want to teach in class again, I can't do that in Thailand since I'm considered too old!) Link to comment Share on other sites More sharing options...
