Problems sending mail from Fastmail
  • Resolved
    Resolved

    Fastmail has repaired the fault. They report:

    This incident has been resolved. Network connectivity on a limited set of routes had been interrupted due to damage to a cross-site connection. No mail has been lost as a result of this incident, although external delivery of some mail was delayed. We will be taking steps to ensure future incidents like this will be resolved more quickly.

  • Monitoring
    Monitoring

    We've observed that Fastmail is reachable once again from the Computer Lab network; we are awaiting confirmation from Fastmail that this is a permanent fix.

  • Identified
    Identified

    This fault is also affecting:

    • Mail sent by Fastmail users, from an @cl.cam.ac.uk or @cst.cam.ac.uk address (or other configurations whereby Fastmail sends the email via msa.cl.cam.ac.uk), as Fastmail is unable to connect to msa.cl.cam.ac.uk;
    • Some other types of connection to Fastmail (e.g. web, IMAP) from some parts of the internet, including the University Data Network. As a workaround, if you're in the William Gates Building, you could temporarily use the 'wgb' wifi network to read your mail as that appears to be unaffected (but you still won't be able to send mail via msa.cl.cam.ac.uk);
    • Mail sent via msa.cl.cam.ac.uk from outside Fastmail, to a recipient whose email is hosted on Fastmail (we are implementing a workaround for this).

    We believe this is related to Fastmail's ongoing incident: https://fastmailstatus.com/clji5sqvg99220wtohhj3e2d2b

  • Investigating
    Investigating

    A networking problem between Fastmail and the Computer Lab is causing Fastmail to be unable to connect to our MSA. Users of Fastmail may find that they receive an error when trying to send mail, or that the mail is delayed. We have reported the problem to Fastmail as we believe the fault is Fastmail-specific.
