    We are continuing to monitor the result.

    Our network engineers have put in place a workaround that should allow all users to connect to Fastmail services again. We are continuing to work on the underlying problem, but we expect no further user impact at this time.

  • Update
    Update

    Our network engineers have determined that there is no issue with Fastmail services or with our contracted connectivity providers. The problem may be with a part of the internet backbone or with a specific NBN ISP. We are reaching out to third-party support contacts and continuing to monitor the situation.

  • Identified
    Identified

    We have received reports that users in several Australian locations are unable to connect to Fastmail via NBN. We have been able to reproduce the issue and are investigating the problem. It appears to be an internet routing issue and Fastmail systems and user data are not affected. If you are affected by the issue, you may be able to access Fastmail via an alternative internet connection e.g. mobile phone data. We will continue to investigate the problem and work on full restoration of access

Interrupted access to Fastmail services due to Cloudflare outage
  • Resolved
    Resolved

    Cloudflare has reported that this incident has been resolved.

  • Identified
    Identified

    An outage at Cloudflare, our external web hosting provider, is preventing some users from accessing www.fastmail.com. Users should still be able to access webmail by going to app.fastmail.com directly. Cloudflare hosts a large fraction of web content, so users may also see images or external links failing to load in emails.
