KeyCDN will supercharge your website by distributing your content across several POPs (points of presence).
This way, visitors will retrieve your website content (text, images, etc.) from the nearest POP. That prevents your website resources from overloading when traffic spikes arise.
You can configure KeyCDN account in a few minutes. It also support SSL connections (or HTTPS).
