5/5 stars, would use again
Kalphiter's service is a very fast, easy solution to the most primitive of Blockland dilemmas: How do I host all the time?
Utilizing simple methods for add-on installation, you can be up and running as if it was your own server on your own computer just as fast as it takes you to upload all your crap!
Controlling the server is made as easy as possible with the extemely convenient, cross-platform remote_client.jar. With an extremely clean (yet slightly dated looking) interface, the system allows you to start and stop your server with the click of a button, and evaluate lines of code with yet another. The best part for me, as a scripter, was the ability to see the results of my code with the amazing console viewing mechanism.
Stess tests and strength of the server? I've ran game-breaking code on his servers and only ever had a problem with lag when I was using cityrpg. When I say game-breaking code, I mean deadly syntax-error while-loop disasters.
In addition to that, I ran a webserver on my server for a few months, and all problems with it could be traced back to my own code, no limitations or issues with Kalphiters service.
All in all, I was very pleased with my use of Kalphiter's servers, and, provided I had the money (Don't get me wrong, his prices are amazing too) I would buy again.
