We are preparing to get into 2016 with a punch. We have migrated all web hosting clients to a new web hosting cluster, which is designed from the ground up to offer high availability and load balancing for all hosted websites.
The new cluster is based on a clustering filesystem, which will remove our 1 minute replication delay between servers allowing you, as a client, to enjoy immediate replication of uploaded/created files across the cluster. In the past, when you uploaded a file you could get up to a minute of delay between what you have uploaded and what appeared on your website, due to a 1 minute delay for the replication across the old hosting cluster. This is no longer the case. The clustering filesystem we now use allows for immediate replications across the entire cluster, with the ability to also do geographical replication, that means replicating data across datacenters, even if they are not on the same continent.
The new web hosting cluster will be the foundation of our new control panel, a version of which is currently being tested internally prior to the public availability. This new control panel has been designed in-house by us, to work according to our customers' and our needs. The base focus was security and ease of use, and we'll be making it available for all customers as soon as the internal testing is done for it.
The migration was not without problems though. During the final days of a server from the old cluster, an outage affected 3 (three) web hosting clients. In total, about 20 websites were affected. Those websites have now been migrated to the new cluster, and the problems have been resolved. We are sticking by our uptime guarantee, and affected clients will get a one week free extension to their plans.
In front of the new web hosting cluster, are a newer generation of load balancers. These load balancers were designed to offer caching support, for a speed up of hosted websites when they are under large loads, but also offer us the ability to add a web application firewall in front of all hosted websites. This feature is slowly being turned on for all clients, because due to the nature of a web application firewall, there is also the possibility of false positives, and we would like to test the WAF before putting it into mass use. A number of hosted clients already enjoy the benefits of the WAF though :-).
