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: Dallas unexpected reboot of opal4

opal4.opalstack.com (Dallas shared hosting) rebooted unexpectedly a few moments ago as around 12:25 UTC. The server is back online and operating normally at this time.

  • Opal4 has remained stable for the past several hours. We haven't been able to determine the precise cause of the unexpected reboots earlier today but we suspect it was a possible fault in the server's remote management interface. We've reset that system and are seeing further no problems at this time.

  • opal4 is back online at this time. Our investigation is still in progress.

  • opal4 is once again offline for troubleshooting and maintenance. During this time, the server may be placed into a rescue mode where it will respond to ping, but SSH connections will fail and other services will not be available.

  • opal4 is experiencing heavy load at this time.

  • Opal4 is back online at this time, the investigation is ongoing.

  • opal4 is now being taken offline for emergency maintenance.

  • The server was rebooted again unexpectedly, we're investigating the cause.

  • We've lost connectivity to opal4 and suspect another reboot, we're investigating further.
