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: Frankfurt opal5 not responding

Opal5 (shared hosting in Frankfurt DE) is currently not responding to web and SSH requests. We're investigating.

  • Opal5 is stable following the reboot. We'll continue to monitor.

  • Opal5 is back online, we're still investigating.

  • We're rebooting opal5 at this time.

  • The high load condition has returned so we're continuing our investigation.

  • Opal5 is back online. The problem was high load caused by heavy disk I/O activity due to high swap usage by a customer process. We've increased available swap and are working with the customer to resolve the issue.
