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.

Past Incidents

18th August 2025

Web: Washington D.C. MariaDB offline on opal1

The MariaDB database service on opal1.opalstack.com (Washington DC shared hosting) is currently offline. We're working to restore service at this time.

  • We've seen no further issues with MariaDB on opal1.

  • The restore is 100% complete and the server should be online and functioning. We will continue to monitor.

  • The restore is 50% complete.

  • Following the integrity checks the database service remains unstable, so we're now rebuilding the system via a full dump/restore of all data. The database service will be unavailable until the restore is complete.

  • The database service is back online. We're now running integrity checks on customer databases.

    Microsoft blocking mx1.us.opalstack.com and smtp1.de.opalstack.com

    At this time mail sent from our DE SMTP server and mail forwarded from one of our US MX servers to outlook.com, hotmail.com, and live.com is being blocked by Microsoft. We're working with Microsoft to correct the problem.

    In the interim:

    • DE SMTP users can work around the SMTP block by configuring their clients to use smtp2.de.opalstack.com as their outgoing mail server.
    • US customers who use mail forwarding can work around the MX block by creating new MX records for mx2.us.opalstack.com with priority 5 and mx1.us.opalstack.com with priority 10.
  • The US MX block is now clear.

  • The DE SMTP block has been cleared.

    We're still working with Microsoft to clear the US MX block.
