The customer support is great, they are always willing to help out with anything I need. If you're looking for a CDN service that will take care of your most basic needs (i.e., caching), this might be perfect for you. We had some issues in terms of speed with our site not loading properly because we were using Cloudflare as an SSL provider - which was causing problems. This caused us to lose traffic from Google rankings due to slow load times. After switching over to Pagecdn and implementing their recommendations, everything has been running smoothly since then!
