High ping loss and connection problems

[MarcSerra]

As you can read on centos forums we got connection problems on 1 of our servers. Making an horrible experience work with our websites, plesk panel, ftp, and all of other services.

Ping results from an office connection to the server (windows machine)...

sent = 946, received = 530, lost = 416
    (43% lost),
Times:
    Min. = 48ms, Max. = 125ms, Med. = 54ms

From another office connection to the same server (linux machine)...

    10 packets transmitted, 4 received, 60% packet loss, time 9012ms
    rtt min/avg/max/mdev = 0.240/0.256/0.296/0.030 m

If we ping from our server to the internet (google) got variable results...
