Not sure that’s the case. Something is broken.

Gone again for us and at least 1 other.

Works from a TPG connection even though resolving to the same IP - 13.107.136.9





BGP routing table entry for 13.107.136.0/24

Paths: (1 available, best #1, table Default-IP-Routing-Table)

Seems like they inserted a bad CNAME into the record for most tenants briefly. Looks like it's fixed now but the DNS caches are still catching up.

Scratch that. Seems to have come good just as I pressed send. Was broken for about 45 minutes.

Did get some confirmation from another network that was seeing the same.

Hi All



Is anyone else seeing Vocus drop traffic to some Microsoft services starting about 40 mins ago? Specifically, Sharepoint Online.



Example IP: 13.107.136.9
