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: multiple locations Service disruption caused by firewall issue

About an hour ago we deployed a firewall update that had the unintended side effect of blocking our resolving DNS servers.

This caused various issues on customer sites on shared hosting, usually showing up as a "504 Gateway Timeout" error.

The issue has been resolved and all customer sites should be working now as they were prior to the change.
