Server management and WooCommerce specialist required

We are looking for someone to investigate an issue with our dedicated server.
It seems to keep going down and some of the processes like catalog updates are causing it to overload.
It runs 3 wordpress sites and is hosted on Ubuntu.

If you have experience with problem solving on dedicated servers please place a bid.

We are looking for someone UK based and with excellent availability for regular server monitoring and management. Please include on your bid your proposed hourly rate for ongoing tasks.

Thanks
