International Internet Problems

[p3rs0n]

Hi, I need some help analyzing the following trace route to a WoW Server is the USA. (US-Stormrage/Texas Data center). I have a 4mb Telkom line and a 10GB Shaped SAOL account.

I have asked Telkom to test my line and I have asked SAOL to help, but they just refer me to each other. It has been like this for approx. 3 weeks, and I didn't change anything on my side. Any ping/speed test to any international server has similar results of pings north of 800. Pings to JHB/CPT are only 30-40ms. In-game ping is between 1000 and 5000 for WoW, so it is useless trying to play.

That is a very congested route between SA and London (AS6453 is Tata Communications, Mumbai).

It is likely that traffic to that site has been allocated this routing for some reason. (If it was only recently I would say SEACOM).

Your ISP should regularly update their routing to avoid congestion like this.

I don't think its a Telkom problem, since there are no delays on any circuit that belongs to them, and if it was your DSLAM your local pings would be affected.

For the record: I get 360ms to the server via MWeb (SEACOM and CogentCo).

Found this tracert from 27/4/2010 @ 01:40 AM. Can my shaped account cause this massive difference between day and night? PS: Previous posted trace was @ 10:33 AM Today (01/05/2010)

Different ISP's can (and do) use different routing for high and low-priority traffic. As I said, AS6453 (Tata Communications) is heavily congested, since it carries a lot of traffic from India via the Middle East.

The congestion may also be a spillover from the SEACOM outage, and re-routing has not yet taken place to this site. I am not familiar enough to comment on your ISP, but 160ms is the latency you SHOULD be getting on the London hop (all other things being equal).

Edit: There is also a thread saying Cybersmart is very slow on the London route, which may be related:
