Title: Users may be unable to access SharePoint Online

User impact: Users may be unable to access SharePoint Online.

More info: As a means to avoid the issue while we resolve the problem, some users have had success changing their DNS address server configuration settings to 8.8.8.8. This can be completed by performing the following steps on a per-user level:

1 – From the Windows Start menu, proceed to “View network connections.”
2 – Identify the network connection you’re using, right click and select “Properties.”
3 – Uncheck Internet Protocol Version 6 (TCP/IPv6).
4 – Highlight Internet Protocol Version 4 and select “Properties”.
5 – Select “Use the following DNS server addresses”.
6 – Under “Preferred DNS server” input “8.8.8.8”.
7 – Press the “OK” button.

Current status: We’re continuing to review the offending change to confirm if our aforementioned hypothesis is the actual root cause of the issue. In parallel, we’re assessing available mitigation actions to perform in order to remediate the impact.

Scope of impact: Users attempting to access SharePoint Online may be impacted.
