It's probably been blocked by your firewall. There are many firewalls, so I won't attempt to tell you how to fix it.

the time I accidentally entered my ip into csf blacklist (instead of whitelist) I needed kvm hooked up just for 5 minutes of work.
 
Good point. Be careful when adding your own IP# to make sure you're adding it to a whitelist, and not a blacklist.

If you've got more than one system you can shell into one which works, and then from there into the one you've accidentally blacklisted, and stop the firewall from the command line, but not all of us have the luxury. Or if you've got a static /29 (we do, temporarily log in from another one of your IP#s. Our provider only charges us an additional $5/month for a /29 over a /30, so we pay for it happily to have the safety net.

We've recently starting provisioning only servers that come with IPMI so we have a built-in visutal KVM in all our new servers. When our old servers are all decommissioned (next few months) we'll be able to log into any machine in the DC without help or expensive dedicated KVMs.

Did your ip changed then or something? Because normally if you install CSF, your ip will already be added to csf.allow automatically.
If you put it in csf.deny now, it will remain in there until somebody disables the firewall for you, get it out of there or if you get access via another ip or method like KVM for example.
