    After upgrading to 10.10 I have a lot of issues with DNS, when you're working from home.
    Some internal resources doesn't resolv, and you can't access them nor via web, nor via ssh or whatever.
    For example, my /etc/resolv.conf contains 2 DNS servers which I receive from VPN and one from my wireless router.
    I've run tcpdump and in some cases (1/3) it sent DNS request not to corporate DNS but local DNS, after that receive 'nx-domain' and browsers, ssh - anything doesn't work for some time with this resource (for 5-10-15 minutes).
    Everything was great at Maveriks. This bug annoying more than any another minor changes...

    I suppose, that it's connected with changing system resolver, probably they want to do resolver better (not sent only to one NS, but for all), but in some cases, then DNS split is needed - it's the worst solution.
