At the same time, two sites with the same topics were cut down. WordPress. What could it be?

Question

PHP

Hello. For about 10-15 minutes, two sites on the same theme for wordpress turned off at the same time. Topics downloaded, not purchased. I call the hoster, he says that he sees that the sites do not respond by timeout. There is a request, but the site is processing something big. They just put a file in the root of the site, it opens without problems. The host assures that there is no problem on their part. Website problem. But just worked, and suddenly went out at the same time. Turned on the same way after 10-15 minutes. Question: can these be viruses built into the topic, (and since the topic is the same on both sites), they simultaneously started doing something ... if so, how can they be calculated and removed from the topic?
Thank you.

And laughter and sin.
In free themes, it is not customary to think over such things as the ability to disable a service. However, in paid ones too. This is implemented exclusively with the light hand of theme developers (no), or when ordering a site (from responsible guys).
It is necessary to search in the direction of such dependencies. For for viruses the hoster would be the first to scream with a greater probability. And some, by the way, sometimes suggest what exactly gives such a timeout (I have met one hoster so far).
