Clouvider vs Netcup vs Vultr
I'm looking to get a new server in the EU for my project and so far I narrowed the list down to these three providers. I do have servers from other providers such as OVH, Hetzner, etc as well. Lately, I've been trying to find and read more reviews about Clouvider, Netcup and Vultr but haven't found that many or recent ones.
What I'm interested in most is the uptime (network and hardware together) and I know nothing can be guaranteed but I'm curious which of the three companies you had the highest uptime with. How often are the planned maintenances and how much they usually take? Which one of the three has the fastest support? Will probably never need it but if some node where my server is hosted or something has issues a fast answer would be preferred rather than waiting for countless hours.
Performance wise, they are pretty similar as far as I've seen. The root servers from Netcup do offer a lot of resources for a cheaper price but that's not as important. I'm hosting a TCP app so I won't be able to make some HA setup with multiple servers, only one server will be used.
