I called them twice. They only said that they can't do anything since my domain name doesn't point to an ovh ip address. And that i have to check with ezoic why the ip address is blocked.
When i access the website, the ip address i get is never mine but always an ezoic's address, for instance 15.236.137.228, which is according to the list here :
52.20.63.25
3.225.202.138
3.217.200.190
54.212.71.227
52.12.170.68
34.218.21.81
3.7.90.144
13.127.240.219
18.139.6.69
18.140.184.0
3.106.6.164
3.106.176.6
13.237.131.67
15.222.77.144
15.222.108.52
18.157.131.187
18.157.105.182
3.126.25.160
34.248.174.237
52.16.85.139
34.255.61.232
15.236.165.82
15.236.137.228
15.236.166.30
18.228.20.129
18.228.107.195
One of ezoic's ip, and every time i get an ip from this list, which indicates the ip addresses from ezoic are being banned. There's no way ovh banned 70% of my audience as it would represent 3000 people banned a day, for suspicious activities. Now the only issue i can think of is to go back to ovh dns as it's less time consuming than changing my hosting provider.
I can make a screenshot with the ip address blocked by ovh, it's always an address listed in ezoic's ips.
Thank you
