Google IP address ranges have been blacklisted by Russian authorities over the weekend as they attempt to close down all channels by which Russian citizens can download and use Telegram, the encrypted communications app.
It comes after a court order issued a week ago that made Telegram illegal in Russia because the company refused to hand over decryption keys to Russian authorities.
It claimed it needed access to communications over Telegram in order to fight terrorists. Roskomnadzor, Russia's communications regulator, claims that Telegram poses a threat to the country's national security.
Over the weekend, it added a number of Google IP addresses to its blacklist of banned websites and applications that, it claimed, violated Russia's recent Telegram ban - wreaking havoc with the online services of businesses across the country.
Last week, the regulatory body ordered Apple and Google to comply with the ban by preventing Russian citizens from being able to download Telegram from their app stores.
While neither Google nor Apple has signalled that they have banned the app from their respective App Store and Google Play Store, it is believed that many websites and services across Russia have been affected by the ban.
According to ABC News, Roskomnadzor implemented a nationwide block on eighteen networks - including those from Amazon and Google - that it suspects Telegram of using to bypass its recent ruling.
Writing on Twitter, the watchdog said it has blocked a range of Google applications in the aftermath of the Telegram ban.
It said the firm has "not met the demands of Roscomnadzor" and "continues allowing the Telegram Messenger Limited Liability Partnership company to use its IP addresses for activity in the Russian territory".
The agency explained: "Due to this, Roscomnadzor has included in the registry of banned information a number of IP addresses of Google, which are used by Telegram to carry out its activity in Russia."
Speaking to TechCrunch, Google confirmed that its services - including the Search and Gmail Android apps - have been affected by the ban.
"We are aware of reports that some users in Russia are unable to access some Google products, and are investigating those reports," said a spokesperson for the firm.
Today, though, the regulator has indicated that it will talk with organisations affected by its blanket blacklists in a bid to resolve the difficulties caused across Russia as a result.
