According to the recently enacted laws, services like Zello need to be registered with the government, require the storage of Russian user data in Russia, store user communication content for six months and metadata for three years, and encryption services also require sharing of keys with law enforcement agencies.
According to the report, in order to completely block the Zello Russian regulators, ISPs are required to block 15 million IP addresses, of which approximately 13.5 million belong to the cloud giant Amazon. If it is true, this requirement can be extremely extreme.
