[AusNOG] Anyone know about TPG's reported routing issue?

[Ross Fawcett]

This mirrors what we saw, had a range of clients reporting remote access was broken, all were found to be on iiNet/TPG and seeing much higher than normal latency and some packet loss. Users were seeing 140-150ms of latency compared to the normal 2-5ms after the issue was resolved.

>From the limited testing we were able to do before it was resolved, it seemed to be affecting the iiNet/TPG -> Telstra clients the worst, but also saw it on my personal link though not to the same degree, 50ms compared to a normal 5-10ms on Node1, which seems to be via AAPT.

Yep, we saw very strange traceroutes sourced from AAPT Internet services with traffic to some destinations looking like it was going between back and forth TPG/AAPT and Optus routers multiple times before making its way to the destination network (with significant latency and packet loss).
