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: Phoenix MariaDB down on opal7

The MariaDB service on opal7.opalstack.com (Phoenix AZ shared hosting) is currently down. We're attempting to restore service and will follow up as soon as possible.

  • The recovery and repair is complete and the MariaDB service is operating normally.

  • The cause of the MariaDB outage was corruption in the service's InnoDB store.

    The service is now operational while running recovery and repair routines in the background. We expect the recovery and repair to take several hours but the service should remain operational in the interim.

  • The MariaDB service is back online at this time but service may be intermittent as we continue to troubleshoot.

    • Web: Frankfurt opal6 under heavy load

    opal6.opalstack.com (Fraankfurt shared hosting) is currently under heavy load and is responding very slowly. We're attempting to identify and correct the cause at this time and will follow up when more info is available.

  • The server is back online following the reboot. The cause was a runaway Apache httpd process consuming all of the server's available RAM.

    We'll identify the site that caused the problem and will work with the site owner to prevent the problem from occurring again.

  • We're unable to troubleshoot due to the extremely high load, so we are rebooting the server at this time.

    Web: Washington D.C. Intermittent network connectivity to opal12

    At this time network connectivity to opal12.opalstack.com is intermittent and customer sites may be inaccessible. We're investigating at this time and will update when more information is available.

  • We've seen no further issues.

  • We've identified and blocked an abusive IP address that was saturating the network. Connectivity is stable at this time. We will continue to monitor.

  • Connectivity is failing again, we'll continue to troubleshoot.

  • opal12 is back online at this time. We suspect that a network issue upstream in the data center was the cause. We're awaiting confirmation and will continue to monitor.
