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.

DNS: USA Partial DNS outage.

During a routine DNS update our Secondary DNS provider captured an incomplete zone update and propagated it. This means that various DNS services for opalstack.com services (DNS, Mail, and Web) are inconsistently available.

We have removed the Secondary provider and we expect this to resolve over the next hour as the DNS TTL caches time out.

  • The DNS issue is fully resolved now.

    Note that while this issue affected only the Opalstack US name servers and only for the domain opalstack.com. Since all of our regional services use the opalstack.com domain, effects of this issue may have been seen by customers outside of the US.

    If you're still having trouble connecting to Opalstack services then please try flushing your local DNS cache
