   Our internal monitoring shows that latency has returned to normal levels as of ~6:30 pm ET. Emails previously delayed have been processed, and no customers have queued messages. No messages were lost. Twilio Sendgrid confirmed to Braze at 6:42 ET that this is what they are expecting. We will continue to monitor this to ensure the issue does not recur until we have more details from Twilio.
