The MaxCDN Content Delivery Network efficiently delivers your site’s static file through hundreds of servers instead of slogging through a single host. This "smart route" technology distributes your content to your visitors via the city closest to them.
MaxCDN has always used a Perl-based system for provisioning zones to various Points of Presence (POPs) throughout the cache network. The current system started to creak as our client base grew: the provisioning happened on a single thread, and blocked on I/O operations.
