Monitoring
We have identified an issue that caused a small increase in latency in email sending for a few minutes, starting at around 5:52 PM UTC and ending at 6 PM UTC. Emails sent during that time will have experienced increased latency.
We have taken the necessary actions to fix the issue and no emails have been lost. We're monitoring the performance of email sending to ensure the latency is back to normal.
