Scheduled DE IMAP/POP3 email server downtime

On 24 September 2026 at between 07:00 am and 10:00 am UTC our network team will be relocating one of our mailbox storage servers to a new location within the data center.

The server will be offline during the relocation. As a result, some customer mailboxes will be unavailable for up to 3 hours during the relocation. Affected customers will be notified directly via email.

Affected customers will not be able to check their email for affected mailboxes during the relocation.

No incoming mail will be lost during the relocation. Mail that arrives during the relocation 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 relocation will not be stored as sent mail in IMAP folders on the server.

Customer websites will not be affected by the relocation.

We realize that the timing of this relocation may not be ideal. Customer who would like to have their mailboxes migrated to a different server in advance of the server relocation should contact the Opalstack support team to make the necessary arrangements.

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 email our support team and someone from our team will get back to you as soon as possible.

Web: multiple locations Intermittent PHP-FPM failures on Opal4 and Opal5

We've been investigating intermittent failures of PHP sites hosted on Opal4 (Dallas) and Opal5 (Frankfurt) which result in "503 Service Unavailable" responses on websites. We'll post more details here as they become available.

  • We've rebuilt most of our PHP stack and this issue is now resolved. Updated documentation and maybe a blog post are on the way.

  • Over the last few weeks we’ve dealt with various PHP-FPM related problems. After trying various combinations of fixes to the server, apache, and PHP-FPM itself we’ve developed a new, more stable PHP-CGI stack to replace PHP-FPM. With PHP and WordPress powering large parts of the Internet (and businesses) having a stable, reliable stack for them is critical.

    We rolled the new stack out to all servers yesterday afternoon and found some edge cases we hadn’t found in our previous testing.

    We’ll be rolling those changes out again tonight. While we do there may be a brief downtime of less than 10 minutes across PHP based sites and the update happens. Once the sites are updated we’ll begin monitoring for any breakages that didn’t show up in our testing and fix them ASAP.

    We’ll follow up with a blog post on exactly what we’ve changed and how things are working in the future.

  • Our troubleshooting is going but we've improved the stability of PHP-FPM quite a bit over the past few days and are seeing no customer facing problems at this time. We'll leave this incident open until we're satisfied that we've got this issue nailed down.

  • There have been intermittent PHP-FPM outages on Opal5 in the past several hours. Troubleshooting is ongoing.

  • PHP-FPM for PHP 7.3 on Opal5 was briefly disrupted about 15 minutes ago. We'll continue to troubleshoot and monitor.

  • We've just deployed a potential fix and will continue to monitor.

    Web: Dallas Opal4 (Dallas) offline

    opal4.opalstack.com located in Dallas TX is currently not responding to ping. We're looking into it and will follow up on this post with more information as it becomes available.

  • The data center has reported that the issue is resolved.

  • Opal4 is back online. We will continue to monitor.

  • The data center reports "an outage related to a networking maintenance that was intended to be non-impacting in our DAL-12 datacenter".

    We're awaiting further updates at this time.

  • The outage appears to be upstream in our data center. We've contacted them and are awaiting their response.
