Why is the site of the livechat online service periodically not available in Russia?

Question

Computer networks

Good day everyone!
why the site of the online chat service livechatinc.com several times a day is either available or not available for several hours, but it is always available through a proxy or vpn, I noticed that from time to time the site is not available only from Russian ip addresses, I checked it in the black list There is no Roskomnadzor,
packets are successfully transmitted through ping, even when the site is not accessible from the Russian ip
in the support of the chat service, they say that there are no problems on our part, maybe your Internet provider is blocking the site
, what could be the problem?

Answer 1

The site itself may not be on the black list
But there are all sorts of amazon aws, cloudflare in emergency
So it turns out and there is no access
Better call the provider and ask him
Do a tracert with and without vpn
And see where the packets do not go
What kind of ip can you see on the 2ip site and with using google
