Skan, a reply to your email ticket was given yesterday.
Is there any problem with the server?
I don't run any special scripts that could harm the website or server, just my regular set of scripts.
Error 403 usually means that your IP address is blocked by the server. As a protection against inexpedient script usage (namely post/.get requests), uCoz has the protection system that blocks the user's IP that refers to the server more than 2 times per minute.
Please make sure that the scripts on your website don't send automatic requests to the server more often than once per minute simply when a visitor is on the website or when he moves a mouse cursor. Only one, maximum two such requests, that work immediately after a page is loaded, are allowed.
When you get error 403, you can try to access your website through a proxy.
counter yadro. something with statsdb.club
Google'd it [yadro] and I found that it's a [potantial?] virus related to webserver and not my pc, made a full sweep on my website for this thing and I didn't find anything
Those are statistics scripts used by uCoz, they are safe.
If your website loads slowly for you, please check what resources cause this in Inspect element > Network (right-click on the page to access the 'Inspect element' menu). You can also use the following service to test the website load speed: http://tools.pingdom.com/fpt/
