A customer called to report no connection. At 9 PM, after a really tough day. The SLA doesn't require me to pick up the phone, but I did. They've been redecorating and mixed up cables. Fried the router with 48 V POE. Explained to them how to bypass the router using the cable to connect to a laptop and at least they can get their work done. Poor kids, no Wi-Fi. Asked them to engrave a nice comment on my gravestone.
