(in fact, he did not block himself, but his SSL certificate provider)
As it turned out recently, relying on the decision of the Oktyabrsky District Court of the Stavropol 2013 (!), Roskomnadzor entered the resources of Comodo, a software manufacturer, in the register of prohibited sites, incl. free antivirus and firewall and one of the largest SSL certificate providers in the world:
crl.comodoca.com/COMODORSACertificationAuthority.crl0q (in the registry)
crl.comodoca.com/COMODORSACodeSigningCA.crl0t (in the registry)
crt.comodoca.com/COMODORSAAddTrustCA.crt0 (in the registry)
crt.comodoca.com/COMODORSACodeSigningCA.crt0 (in the registry)
secure.comodo.net/CPS0C (in the registry)
')

Roskomnadzor, on the basis of a 2013 court decision, blocked the resources of the largest SSL certificate provider
Moreover, government sites do not work, for example, I wanted to go to the site -
Construction Control
If you erase from the address https: // everything works, however, search engines, in particular Google, provide links with a secure connection. Therefore, we have come to a situation where uncontrolled blockages by the government began to hurt the government itself. If a person wants to go to a resource by finding it through Google - he will think that the resource is not working or he has got on a fraudulent link.
In fact, all sites work without https, some with a Comodo certificate work despite blocking - for example,
mos.ru Or a public services site, although I think it still depends on where the link opens, most likely on some devices, both sites open without forced confirmation or turning off SSL will not (by the way, public services without SSL do not work)

And why does
www.gosuslugi.ru work
PS. Operator Onlime

PS2. Roskomnadzor has already deleted these addresses from the list of
reestr.rublacklist.net/search/?q=comodoBut it will take some time until the lock is turned off for all operators. I wonder how much more parallel sites have been touched?
