Loss of Internet Questions

Spectrum decided to go down for our entire area some time in the middle of the night and just now restored services.  When I looked at the keypad this morning I think it said "no link to base station."  I don't remember exactly what it said and now that service is restored it is no longer there.  Does anyone know what the message would have been?  Also, aside from the cameras, how does loss of internet limit Simplisafe?  Thanks.
