We have around 10 servers in Contabo. 1 of them consistenly have problems. Sometimes due to network, sometimes maintenance, etc. I am not sure why but this is the reason that some of the users are pretty happy some of them not.
I’ve one server in Digital Ocean, never had a problem.
At the end, with Contabo or not we need to have backup strategy. This one can be a starting point Automated continuous master/slave streaming backup
