The problem should be resolved.

Their technicians are still actively working on the situation with no ETR as of now.

We are experiencing some network disruption on our servers in Contabo's in the Dusseldorf Data Center and this instability in the network may most likely lead to a slower connection. Their technicians are already on site and investigating the issue.

We humbly apologize for the inconvenience caused by this matter.
