How to solve problems with website blocking
On June 4, due to the actions of intruders, the social south africa whatsapp data Odnoklassniki and VKontakte, as well as the websites of Russian Railways, NTV, RBC and Channel One were blocked. The reason for the incident is a long-known vulnerability in blocking prohibited resources by IP address. Some providers use it to save money and minimize the efforts to create a blocking system, in which the owner of a prohibited Internet resource can restrict access to any site on the Internet.
And a similar situation may happen again, because not all providers use modern methods of filtering resources that are in the unified register of prohibited sites of Roskomnadzor and in the federal list of extremist materials of the Ministry of Justice.
Below we will discuss why permitted sites are blocked and what measures providers and telecom operators should take to avoid this.
Why are allowed sites blocked?
Each domain owner has access to configure their DNS records, including if this domain is on the Roskomnadzor list and is blocked by all telecom operators.
The owner of a blocked resource can register IP addresses or CNAME names of any permitted sites in their DNS, after which they will also be automatically blocked by all Internet providers that use the IP blocking mechanism, since when using this type of filtering, the provider is forced to independently receive a list of IP addresses for prohibited resources from the DNS server. It is difficult for the provider to determine whether the IP address it received belongs to an intruder or a legitimate resource. The same principle applies to the "Auditor" verification system, which is responsible for monitoring the implementation of blocking by providers and transmits information to the territorial office of Roskomnadzor.
