A few people are expressing slight unhappiness at not getting a new account. If you’re one of those we’d just like you to know that it’s from necessity not spite. Below is a graph of the CPU utilisation on the sipsorcery.com server. The red line is the CPU and the top of the graph is 100%.

The reason for the high utilisation is a problem we have with the database access software. If/when we can get it solved CPU utilisation is expected to drop to more like 40 or 50%. At that stage we’ll open up the system for new accounts again. In the meantime the trickle for new ones is the only way to keep the service available for anyone.

Yes we could use a bigger Amazon EC2 instance or spread the load to multiple instances but then the cost of running it starts to go above what is viable for a free service.
