Hello! Since 2 days ago, i can agree the mitigation from ovh is stronger, but sometimes can not be scanned this server.

https://www.gametracker.com/server_info/server.csomod.com:27015/ with ip 135.125.249.130

I am the owner of the game hosting server, not owner of the server. Those ip are allowed and sometimes scan is stuck. I already saw thread: https://www.gametracker.com/forums/forum.php?site=1&thread=182942

This is not related to gametracker bug rather the mitigation issue. i see your server faces attacks and it gets down and thats the reason the scan is not happening which obvious would show offline. OVH anti-ddos is indeed very strong agreed but it depends on the gaming profile what they set you in. If you can give OVH a call to have a look to have some tuning on profile for your server ip then this issue might get fixed.

In order to make call, you should have valid account in OVH customer panel with the server ip as your product/services . As i see you mentioned you are the owner of game hosting server then this would be better for you to fine tune the mitigation game profile for the server ip that has issues.

Note: UPDATE below

The attack you facing is layer 7 [application layer] attacks which as of now OVH has no protection confirmed in support ticket. so you need to sort it yourself like adding iptables/firewall configuration that does rate limit and many such.

OVH anti-ddos team has plan to release a new version soon which will fix all the issue faced by most server owners by the A2S attacks which puts strain to the server causing high cpu spikes which makes server appear offline.

What is A2S ?

I called them 10 min ago. Thank you, i know about A2S attack, Tsource engine query. Believe me, in Romania, this attack is pretty much used. For most, in combination with iptables, cacher and reunion, players can be limited, client favorite problem and more.

true , this is same issue i was facing. after 2 years of struggle finally for me OVH solved. but it took time to see data and make proper judgement.

A2S is one of the thing that queries the server , but some attackers take advantange and use that to make the CPU high spike .

For moment OVH has no real protection for this kind but if you give them some data called tcpdumps from your end , they can do some adjustments which will work for you .

The cpu usage can be solved with cacher + reunion, but yes, depends by tcpdump and more.

yes but side effect would be your server appear offline for others and GT.

Solution would be to get OVH do adjustments for you in order for your server to appear scanning always.
