Sendgrid's mail service is working again, but in a degraded capacity. Once again, brainCloud is fine. We are going to close this incident from our side.
Update from Sendgrid - At this time, we are receiving and delivering mail as expected (NOT including Legacy or New Marketing Campaigns). Due to an issue in one of our data centers this morning, mail received from approximately 6:00AM MT - 6:15AM MT is still stuck in delivery. We are working to get those delayed messages delivered as quickly as possible. Customers may still see errors with non-mail send related API calls. Our app.sendgrid.com site and signup is still down. We sincerely apologize for the inconvenience and thank you for your patience. We will provide another update in 30 minutes or sooner as we get updates. Please reach out to our Support team at https://support.sendgrid.com
with any questions.
