Investigating

We are aware of a recently disclosed Linux security vulnerability and are working to apply the relevant patches across our infrastructure.

At this time, we have no evidence of any attempts to exploit this against our systems.

As a precautionary measure, we have temporarily disabled SSH access to our hosting and managed cPanel servers while patching is carried out. All other services remain fully operational.

We will update this notice once patching is complete.
