How to solve the problem with the increase in requests for hosting?

Question

Network administration

I use Ukraine hosting services, recently I received a letter from technical support stating that "The account consumes more than 100 processor minutes per day and creates problems in the operation of other sites located on the server", and the answer came that, "the reasons why search engines began to actively crawl the site are unknown" . And now I don’t even know which way to dig to fix it. Nothing has changed on the site during this period. What could be the reason and how can it be fixed so that there are no more such problems?
ps offered as an option to switch to a business tariff, but it is 4 times more expensive

Answer 1

Change hosting to any other. VDS costs a couple of bucks a month. Hosting provider of any choice.

Answer 2

The easiest way is to change the host to something reliable, with which there will be no such problems.
I can advise Xelent, I do not think that it will be much more expensive, but such problems will not arise. + I am sure that you will feel a performance increase, because there is a large-scale data center and hardware at the level
