"Resolving host" slowdown

[krenp]

This problem just surfaced; I've been using OpenDNS on our home network for years.

Mac computers, using Chrome, get "resolving host" message for every site, including this one. All pages taking forever to load.

Nothing has changed on our end. 

I've tried clearing browser history, clearing DNS cache, rebooting. Can't shake the problem

Other suggestions, please?

Thanks!
