Thoughts
As it turns out this outage was more than just Microsoft Teams. It also affected Exchange Online and the Office 365 Portal Too!
If you are utilizing native Microsoft Teams Calling Plans and Teams via Office365 as your phone system what is your backup plan when this type of scenario happens?
For providers who offer Direct Routing via Microsoft Teams at least you would have an alternative option to route calls at the very least call forward numbers.
It's worth thinking about what all IT and MSP's usually do, what are our options when an issue occurs! In the world of Cloud and Tech we all know nothing is 100% ... 100% of the time!
