Updated central database server

In order to improve the speed of the hosting control panel, we have updated the server that runs the central database. Now the database uses a server with four 8-core processors. We preferred a smaller number of cores and a higher processor frequency so that each request would be processed faster, and the parallelism of execution would be increased due to the large number of processors. SSD disks with NVME interface are used as a file system, which are excellent for processing data in a database. MySQL version has been updated from 5.1 to 8.0.

In the near future we are planning to update the central web server.
