Scheduled network maintenance for opal3 and opal8

On 20 August 2026 between 11:00am and 4:00pm PDT (UTC-7) our data center team will be upgrading the racks that host the following servers:

  • opal3.opalstack.com
  • opal8.opalstack.com

During the 5-hour maintenance window, network connectivity to the affected servers will be interrupted for up to 1 hour during which websites and other services hosted on the servers will be unavailable.

Email and DNS services will not be affected.

The hosting control panel will remain online, but will be unable to apply changes to your services until connectivity to the server is restored.

Affected customers who would like have their services relocated to a different server prior to 20 August 2026 should contact the Opalstack support team to make the necessary arrangements.

Scheduled US IMAP email server downtime

On 26 August 2026 at between 11:00 am and 4:00 pm US/Pacific time our network team will be performing infrastructure maintenance. During this 5-hour window, network connectivity to one of our US IMAP/POP3 email servers will be interrupted for up to 1 hour.

As a result, some customer mailboxes will be unavailable for up to 1 hour during the network interruption. Customers who will be impacted by the interruption have been emailed directly.

No incoming mail will be lost during the interruption. Mail that arrives during the interruption will be deferred and delivered once connectivity to the mail server is restored.

Email forwarding and SMTP services will not be affected, however messages sent via SMTP during the interruption will not be stored as sent mail in IMAP folders on the server.

We'll update our status page at http://status.opalstack.com/ at the beginning of the maintenance window. To be informed of system status updates automatically please subscribe at https://status.opalstack.com/subscribe.

If you have any questions or concerns regarding this maintenance then please contact the Opalstack support team.

    Email: Germany Incoming mail problems in Germany

    We're receiving reports of slow mail delivery in our German mail system. We're looking into it at this time.

  • The disk array rebuild is complete and the server has been stable since our last update.

  • The DE mail service is back online at this time. The main issue was heavy load caused by the very high volume of deferred mail the resulted from the mail loop. This was exacerbated by the degraded disk array.

    The networking issue was unrelated but has been resolved.

    The disk array is still rebuilding but the server is operating normally. We'll continue to monitor until the rebuild is complete.

  • There seems to be multiple issues related to the DE IMAP server:

    1. A forwarding loop was causing delivery delays for the past few hours.
    2. A degraded disk array was impacting system performance
    3. A failed network switch is currently blocking network connectivity

    Our data center team is working on restoring connectivity at this time.

  • The DE IMAP server is now offline for a filesystem check.
