Scheduled

Purpose: Patching and preventative maintenance.
Systems Affected:

Microsoft:
-Microsoft Teams - Migrate MAPS circuits in Ashburn to new cross-connects and test failover afterward
***Possible Impact: There is no expected impact during the circuit migration. During the failover testing, we will intentionally shutdown primary paths to force traffic over the backup connections and test failover performance. This failover testing could result in a very brief loss of audio or dropped calls.
