Fuck ovh, took 3 days to answer my tickets, back and fort.
If you know OVH, you know that in since of support they are not great, but with Networking and decent dedicated servers, VPS and Web Hosting is pretty fine.
People who uses OVH, should understand they focus in Network, not supporting. I have used them, never have a single problem with them.
SoYouStart / Kimsufi are from OVH. You won't find better prices with quality. OVH is very well know for students and for cheap dedicaded servers with decent Anti-DDoS Filter.
SoYouStart uses Anti-DDoS Pro. I don't know if you have used VPS or dedicated server, they only help you with disk and network replacement on Datacenter.
If you are looking for quality support you may go with Javapipe, BuyVM fastpipe.io or Blazingfast, never forget unmanaged services is "you broke, you fix it"
Hetzner Managed server should be great for you.
Couldn't pay me to host with them again. Absolutely the worst.
Edit: If you do happen to be using them keep a backup of your site. It's stupidly easy for your competition to get you taken down.
If someone of your competition DDoS your website, 1-4 times per day you will be kicked out from network, Easy.
Fake DMCA Complaints it's another.
