Users of multiple VPN services reported widespread connection problems throughout the day as IP addresses belonging to several large hosting providers were placed under restrictions.
The blocks targeted infrastructure used by VPNs to reroute traffic around content filters, causing entire ranges of servers to become inaccessible when whole subnets were affected.
The Telegram channel Exploit reported that more than 20 VPN services of varying sizes experienced disruptions, though Roskomnadzor has not issued an official statement on the scope or origin of the measures.
The affected providers indicated they are shifting customers to backup servers, noting that the restrictions appear selective yet still force frequent address changes during the day.
The incidents coincide with ongoing discussions of new rules that would require hosting providers to independently detect and report masked VPN IP addresses to regulators, a proposal put forward by MinTsifry in early August.
Similar large-scale subnet blocks occurred in late May, impacting numerous MTProto-based proxies and VPNs simultaneously.
