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: Germany Network outage affecting domains that use Opalstack DE name servers

Our DE name servers, SMTP, and several customer VPS located in Frankfurt, Germany are currently offline due to a connectivity issue with one of our regional providers there.

They're working to restore service. In the interim, we are relocating our DE nameservers to new locations.

Since the DE name servers are affected, this is unfortunately affecting all domains that use Opalstack's DE name servers. We're hopeful that service will be restored quickly but if it is not then you may want to switch the NS for your domain to one of our other regional sets of name servers. Our regional NS are listed at: What are your name servers?

We'll update this post as soon as more information is available.

  • All DE services are back online.

  • Service has been partially restored. The remaining affected servers are ns2.de.opalstack.com and 5 private customer VPS.

    We'll continue to monitor and update as the service is restored.

    Web: Washington D.C. opal1 not responding

    opal1.opalstack.com (WDC shared hosting) is currently responding to ping but not to SSH and HTTP requests. We're investigating and will update this post when more info is available.

  • The problem was caused by a spike in system load due to a problem with a customer site. Conditions have returned to normal and we'll work with that customer to prevent further issues.
