Opalstack System Status

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: Washington D.C. Opal1 service disruption

At around 2021-02-18 11:00 UTC today the /tmp partition on opal1.opalstack.com ran out of available space. This disrupted service for applications that needed to write to temporary storage including PHP apps and the MariaDB database service.

At the time of the event our monitoring system was only checking the status of these system services and not their operational performance, so no alert was generated.

We corrected the problem at approximately 14:00 UTC and the server has been stable since that time.

We're updating our monitoring system to perform the tests necessary to alert us to the conditions that caused this incident which will help us avoid this sort of extended disruption.
