Due to changes in the LAN router, I had to modify the static IP of one of our servers. It still succeeds in finding the external world (
ping google.com), but only temporarily - when I access one of the websites hosted in that server through a browser, if that website tries to access google.com, for example,
ping stops returning successful requests.
All computers can still ssh into the server, the problem seems to be DNS-related only: the server itself can't connect to the outside through domain names reliably.

Restarting the networking daemon or even rebooting the computer didn't solve the problem. Also, I don't think that the dhcp daemon is overriding any of those configs, because the problem remains even when I explicitly stop the client.
