   On March 11th, at ~8 PM UTC \(1 PM PDT\), we began experiencing delays in emails sent through Gmail due to server congestion. The issue was resolved at ~9:05 PM UTC \(2:05 PM PDT\) after we addressed the server constraints. While there were delays in email delivery, all emails were successfully sent, as confirmed by checking the sent folder.
