Thank you for reaching out. We are so sorry you couldn't connect - there were some access issues earlier which have been resolved now. We are continuing to work to address the recent issues and apologize for the inconvenience caused. If you are still having problems connecting please let us know.

Yes we will be publishing in the next day or two. Thanks!

Still figuring it out. We will post more details when we have a complete picture.

Thank you, we appreciate that! We hope to be on the other end of this soon.

You have a 14 day grace period on adding payment and renewing, so no worries. Once operations are back to normal you'll be able to add it. 🙏

Thanks for pointing that out - updates are added to the bottom of the post. We'll consider a different way of adding updates 🙏

** Status Update **
We continue to move services to new hardware, including peripheral and less critical services. Email access should increasingly normalize. If you are having difficulties connecting via IMAP and SMTP you may try both Runbox 6 and Runbox 7 webmail interfaces at runbox.com.

Thank you so much for that, your message has been forwarded to the sysadm team 🙏

Thanks for the input, we totally get it. The more information the better. SMTP is having intermittent issues as we are still migrating servers. Have you tried webmail (both Runbox 6 and 7) in refreshed browser window?

All emails are delivered - it is access that has been the issue. No user data has been lost, and queued incoming email is being delivered as quickly as possible.

Update: No user data has been lost as a consequence of this incident, and queued incoming email is being delivered as quickly as possible.
We apologize for the problems this has caused and are taking steps to prevent something similar from happening again in the future.

** Status Update **
The replacement server is gradually being utilized with new virtual machines that are offloading the existing servers where disk replacements are being finalized.
Email service access is normalizing again and most customers should be able to log into web, IMAP, POP, and SMTP.

Our support system is also impacted but we are working to respond to all requests as quickly as possible. If you are unable to receive a reply from us via email you may log into support.runbox.com to check the status of your request. and please follow status.runbox.com for detailed service info.

** Status Update **
We’re addressing compounding hardware issues including disk replacements. This might cause continued slowness for a few more hours. Note that no user data is directly impacted by these hardware issues. We sincerely apologize for the disruption as we work to restore full service.

All services are unfortunately affected intermittently. We understand that the ongoing webmail issues are causing significant disruption, and we sincerely apologize. Our team is working around the clock to fully resolve the problem.

Our latest update: We are experiencing compounding hardware problems and are attempting to work around these to resume normal operations.
We apologize for the problems accessing our services while we work continuously to resolve the underlying issues.
