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.

Past Incidents

17th January 2025

Web: Frankfurt High load on opal15

opal15.opalstack.com (Frankfurt shared hosting) is currently experiencing heavy load. We're working to resolve it at this time.

  • We've identified the cause of the problem and have taken measures to mitigate it as of about 3 hours ago. The server has been stable since that time.

  • The high load was caused by heavy CPU usage from the MariaDB service. We're still working to identify the exact cause but the server is stable at this time.

    Web: Washington D.C. MariaDB down on opal10

    At this time the MariaDB service on opal10 is offline. We're working to restore service and will update this post when more information is available.

  • The recovery is complete and the database service is back online.

  • We've been unable to recover the MariaDB service in-place, so we're restoring the service from the most recent backup which was completed about 13 hours ago at 04:21 UTC.

    The estimated recovery time is 4 hours or less. We'll update this post when more information is available.

  • The MariaDB InnoDB store on opal10 is corrupted. We're still working to recover but do not have an ETA at this time.
