This is probably a "minor point", but something that has impressed me all the same

today, i unplugged my router, and within 5 or so minutes I'd received a text telling me the connection had been lost. When I finally plugged it back in, again, I received a text message saying connection restored
When I was with Entanet, and experienced the outages, on 2 of them I had left work early with plans of "finishing off" when I got home.. if only I'd had this function then
