While generally satisfied with iBurst service I have of late seen a dramatic increase in latency to Telkom/Saix sites via iBurst.

By tracing the route packets take we see a rather SAD state of affairs:

traceroute www.telkom.co.za
1 wbs-196-2-120-1.wbs.co.za (196.2.120.1) 53 ms 63 ms 43 ms

4 ge0-0.br1.jnb6.alter.net (196.30.156.41) 46 ms 46 ms 65 ms

7 telkom-tienet-gw.telkom-ipnet.co.za (196.25.2.138) 360 ms 268 ms 271 ms

So, either their is a problem with the UUNET atm interface or it's simply congested ...

Anyone else seeing this !!??!!
 
Something at iBurst(or other places) is screwed!

Seems SAIX is experencing severe peering problems with IS and UUNET. The link between "other-side.atm6-0sub1.br1.jnb6.alter.net" and "telkom-ipnet.co.za" looks overloaded.
