I'm looking forward to seeing an official response from Linode on this. Hopefully they are fast and honest about it. I've been a happy customer for quite a while, but this is definitely a concern.
They weren't exactly fast and honest the last time a break-in happened. In fact even to this day nobody is quite sure what went down aside from tons of Bitcoins going missing!
They are already way overdue. Their support staff is pretty damn fast, so I'm sure they could have commented on this if they wanted to.
Alas, they have not.
I just blocked my credit card, and Linode will not get anymore of my money. Too bad, i enjoyed my stay very much, but no matter what their response will be, I doubt I will be able to believe them. =/
