[AusNOG] Telstra->Optus routing last night?

[Bob Purdon]

Hi All,

Did anyone else see Telstra handing traffic to Optus last night via
Reach (and hence via the US of A)?  Normal path is Telstra to Brisbane,
and handed off to Optus there.

Anyone know what actually transpired?  Broken peering link?  Botched
announcements?
