Well, that's not really a shocker, now is it?
I tallied up our cancellation requests since the start:
No longer needed: 260 Unused: 144 No IPV6: 41 Up/downgraded plans: 38 Punctuation: 37 Poor Performance, no ticket: 35 Inexperienced User: 32 "Testing": 29 "Thanks": 26 Not Enough Resources, no ticket: 14 Atjeu->CC move: 14 Moved to new provider: 12 "Didn't mean to sign up": 10 Payment Issues: 8 Poor Performance, ticketed: 7 Need BSD/Windows/not-Linux: 7 PI->Atjeu move: 6 Found better location: 5 Not Enough Resources, ticketed: 4 AUP/TOS change 3 Poor support, no ticket: 3 User can't read TOS 1 Poor support, ticketed: 0
Was somewhat surprised at how many people never use their VPS. This doesn't even get all of the users that aren't responsible enough to submit a cancellation request.
