Late last month, Russia started blocking Webtatic.com indirectly because of a unaffiliated online currency website serving from the same IP address.
This was due to Cloudflare (a CDN service), which both this and that online currency website were using, sharing IP addresses across it’s Free and Professional subscriptions between clients. A blanket ban was applied to the IP address to block the offending website.
Sadly Cloudflare were unable to solve the issue, and Webtatic was unable to get new unblocked IP addresses from them.
Due to this, Webtatic is no longer using the Cloudflare CDN, and will instead transition to hosting the website in multiple data centres (as the yum repositories also currently do).
