Over the past couple months, we mentioned that we had a long list of upgrades and improvements that we planned on deploying for our hosting services. Our newest improvement is the integration of Ksplice into all of our servers.
What is Ksplice?
If you are unfamiliar with Ksplice, Ksplice gives us the ability to apply important kernel security updates released by CloudLinux without having to reboot the server.
What does this mean to our hosting customers?
This means higher uptime on all our servers and our customer websites. In the past, anytime a kernel upgrade or security patch was released, we would have to reboot the server. On average a server will take between 5-20 minutes to reboot. On rare occasions the server might have to perform a FSCK (File System Check) that performs a check/repair on the file system. A FSCK can lead to hours of downtime for the server and all websites on the server.
With Ksplice, all kernel upgrades and patches can be applied without a reboot. It even gets better! Ksplice also has the ability to auto update the kernel. This means that security patches will be applied much faster and automatically. The end result being a much more secure hosting environment with much higher uptimes.
We understand that uptime is a critical and we are thrilled to bring this benefit to our customers.
