We've temporarily removed the RU proxies from the Load Balancer. You shouldn't encounter any more issues with this proxy.

We've deployed a partial fix giving the UA and TR nodes more priority on the Load Balancer.

We're currently investigating some issues regarding the EU2 Proxy. This probably doesn't affect you, but if the Load Balancer assigns you one of the RU proxies, you'll see ads for some weird reason. TR and UA proxies are working fine.
