Funny that DO's public response was to demand permission to discuss the case publicly, when apparently they had not discussed it with the customer concerned!
I think they have. The customer in question simply didn't put it in his blog post. I feel as though the customer may be presenting the facts in such a way to make DO look bad. I don't see anywhere in his blog post about his DDOS attack. His server was shutdown because it was running a DDOS attack. My guess is that his server got owned...
People get disproportionally mad when their server gets shutdown, for a service that charges $5 a month for a VPS. Most people probably wouldn't get angry at Netflix if they cancelled their $7 a month account, but shutting down a VPS feels like a personal attack.
If you pay $5 a month for a service, don't expect a customer representative to hold your hand and debug your server troubles.
