US IMAP email server downtime

On 22 July 2026 at 10:00 am US/Central time (UTC -5) one of our US IMAP email servers will be shut down for infrastructure maintenance. The server will be offline during the maintenance and the expected downtime is 6 hours.

Affected customers will be notified individually via email.

No incoming mail will be lost while the server is offline. Mail that arrives during the maintenance will be deferred and delivered once the mail server is back online.

We realize that the timing of this relocation is not ideal. If you have business-critical mailboxes and would like them to be available during the maintenance then please email support@opalstack.com or reply to this message to make arrangements to have your mailboxes migrated to a different IMAP server prior to the scheduled maintenance date.

If you have any questions or concerns regarding this maintenance then please email the Opalstack support team for assistance.

Web: San Francisco opal8 not responding

Opal8 is not responding at this time. We're looking into it.

  • It appears that the earlier reboot was initiated by the system watchdog after the server became non-responsive under heavy load.

    The server is operating normally at this time.

  • Opal8 is back online. The server rebooted unexpectedly so we're investigating further.

    Dashboard Dashboard disk usage stats incorrect

    There's currently a problem with the display of disk usage statistics in the Opalstack dashboard which will cause customers to see reported usage much higher than their actual usage. We're working on a fix at this time.

  • A fix has been deployed. Dashboard usage charts will return to normal in 8 hours when the old data has rotated out.
