Maybe it's just a firewall limiting the number of packages per seconds, very common solution to block DDOS.
You can check the status of udp sockets throgth this command: cat /proc/net/udp Then convert the local_address column to int(hex->int) match your server port, if you are using the default config(port 27015), will be something like this: XXXXXXXXX:6987. Then check the drops column in the same line. If is low(less than 2000 running at least 1 hour, with players), probably isn't a server problem, maybe a firewall, ddos protecion false positive, etc. If is too high, you have a problem in your dedicated server configuration. Check your firewall rules( sudo iptables -L). 2013/11/25 arnold lam <[email protected]> > So the support did another speed test for me.
