A new, faster PUSHR CDN website.


We've been receiving some criticism for some time regarding our website being slow which, let's be honest, is not a great self-advertising for a CDN service. PUSHR CDN does not advertise website acceleration at all among the services that we offer as that is not our specialty, and our website was not accelerated by our CDN. Since a redesign was due, we've decided to host the new website directly on our CDN network and see where this goes in terms of speed, especially compared to other CDN services that claim to specialise in website acceleration.

Introducing Anycast DNS


We are happy to announce that after a month of testing, two weeks ago we've silently released our anycast DNS to all customers. Anycast is a routing method in which a single destination address is routed to multiple endpoint addresses. The shortest network path between the client and the server is being used automatically to ensure low latency and fast connectivity, and in the event of a failure of one or more endpoints, the algorithm will exclude them from the mix, redirecting all requests to the healthy ones. Just like our failover system system does for PUSHR CDN's edge network.

Introducing sub-second cache purge


One of the main ways for a content delivery network to accelerate a piece of content is to cache it on an edge server in close proximity to the visitor. Once cached (usually after the first request) the content is served to all visitors at high speed, without the need to contact the origin, which may be physically located in a distant country or even on another continent. This greatly accelerates the rate at which visitors can fetch a copy of your content and it also allows you to scale seamlessly since all the load from the origin is shifted to the CDN.

However, there is also a down side to caching. Every now and then you may wish to update the contents of a file, or simply push a new version of a software without changing it's file name. Since the old version will still be in the CDN cache, the new version will not be served until the cache is considered expired, unless you let the CDN know that it should fetch a fresh copy.
