[AusNOG] Anyone from Microsoft around? We might have figured out your BGP issues.

[Phil Mawson]

Hi Rob,

The root cause of this issue is not Microsoft, however it appears to be an issue within the TPG network.  This route is not active within AS4826, however TPG believes we are advertising it to them - which we are not, nor have we ever.

We are escalating it within TPG now for them to check.

Regards,
Phil
