Rocket Are we down

Help for Rocket IPTV Server.
Couldn't load the yellow progress bar on my Mag 254 last night, but this morning it worked o.k..

I think it was problem with server.


So next time if that happens how do I know if this is due to problem with server and not from my end ?
So I don't have to waste time re-booting it to try to get it to work if it is due to the server.

Do I ping the server to test it if it is working or not ?

Thanks.
