Update to our users: Routing leak by an unrelated network in Kinshasha DRC caused bad paths to Quad9 for a few EU and NA operators between 12:15-13:40UTC
Liquid Telecom then became favorite path for Verizon, BT, and some Orange France networks, overloading our site in Kinshasha.

A potential routing leak from a provider one or two networks distant from Quad9 may have resulted in several North American networks (so far, only Cox, Bell Canada, & Rogers-and any networks receiving transit from them) trying to send traffic to the wrong Quad9 location.

To protect against this type of risk, all of Quad9's active prefixes are RPKI-signed, though this only protects customers on networks who filter on RPKI validity. Talk to your network provider about their plan or implementation of RPKI to avoid outages via route hijack.
