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.

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.
