I still remember the day that happened to us. It was a Friday and not only did we lose data but our phones were VoIP so no clients could get through to use either. I spent much of the day troubleshooting with their support before I figured out to ask them to tell me what five static IPs they have listed for us in their system. Turns out they changed with no notification and even their internal people didn't know. Spent more time trying to get our old IP addresses back as some of our vendors had IP restrictions and some of our partners accessed one of our internal servers. That turned out to "not be possible" so spent Monday filling out forms to update to the new IPs everywhere else. I think I still have one of their senior VPs cell phone numbers in my phone from the late calls that night including a couple while I was having a party at my house.
