Started on October 15, 2020 at 5:50 PM. Resolved after about 1 hour.
There is an issue with receiving automated incidents using emails *@automation.instatus.com.
I opened a ticket with Mailgun to resolve the issue, and waiting for their response.
Mailgun has added the issue to their status page.
Currently waiting for them to resolve the issue.
Mailgun has resolved the issue and monitoring the situation.
Instatus automation is now working, but I'm waiting for Mailgun to close the issue, so that I can close it too!
Mailgun has resolved the issue earlier. Apps should work as expected now!
