[AusNOG] Vocus dropping traffic to Microsoft?

[Sean Agius]

Just had reports of Outlook desktop clients providing "Admin Notifications", stating issues with Sharepoint Online and OneDrive for Business .. Most likely related to what you're experiencing and would indicate an issue greater than Vocus.

Regards,
Sean Agius

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
