Yes, I have a bat phone. Yes, if backbone routers on certain Verio, AT&T, or XO points goes down, I'm up.
If the network even shows some packet loss, its recorded and monitored. This isn't a hobby, hundreds of thousands of dollars are riding on 99.9% uptime.
We had 3 techs respond last night, and 2 more call me later to check, just from our end of the network. Reprocussions knocked out a remote handoff, there gear was cheap and was unable to route after the lines were back up. Another support call to have them reboot there gear, our end was fine.
I ended up going out to breakfast after we came online, and finilized the purchase of a competitor. 4:30 am is a wonderful time
