The issue is caused by a change in DNS handling by a provider we're using. We were not notified of this change. The change has been handled on our end and we're updating DNS settings for several domains running the Ubivox platform.
Since this issue is DNS related changes take time to propagate across the internet. We expect it to be solved worldwide within six hours and we will keep an eye on the system over the next 24 hours to make sure nothing else pops up.
We're very sorry about the issue. Do not hesitate to contact support if you have any questions.
-- Update 11:54
We have made all the changes to DNS and we're seeing most systems running as expected again. However, due to the nature of DNS changes might not show up on your network just yet. It should all be solved within the next few hours without any actions on your end.
Let us know if you experience anything out of the ordinary.
