The very popular trademe site is uncontactable for most people today.
According to discussion on the network operators group, this is probably because at 11 am today Telstra-Clear depeered from WIX (Wellington Internet exchange).
It is thought this has overloaded AT&T’s Wellington pipe, as much traffic has to go through them now, rather than directly.
Best people don’t keep trying the site. I’ll do an update when it seems problem has been fixed. And oh yeah this is one of the reasons why peering is a good idea – minimises traffic having to go via international circuits.
UPDATE: It may be a denial of service attack, not linked to the depeering. No confirmation yet.
