Retroincident - Domain Authentication Endpoint failures
Incident Report for SendGrid
Starting around 8pm PST on June 11th, we started seeing an elevated number of 500 errors affecting sender authentication endpoints (such as validating domains and records), but these were not related to mail sending API requests.

Changes are being reverted and no further issues should be seen from now on and moving forward.
