i am using GUIminer i get a message from the miner saying "connection problems". I lose connection for only a few seconds.
i can open the website.
i dont know how to ping pit.deepbit.net.
If your using Windoze Click on Start>Run then type in cmd and click ok and that will open a DOS Box. In that type in "ping pit.deepbit.net -t" and press enter. Use CTRL-C to stop it.
Alternatively press the Windows key on the left side of the keyboard and the R key at the same time to get the run dialog.
