DNS Intermittently Works

I am running the latest Home Assistant Yellow with latest version of the OS.

I setup outbound mail via smtp.google.com and everything was fine.
A few minutes later and it wouldn’t work.

➜  ~ ping smtp.google.com
ping: bad address 'smtp.google.com'

Dig usually does work, though times out a couple of times before a result

Also the out-the-box weather card intermittently doesn’t work, I’d imagine for the same reason, no DNS.

➜  ~ dig smtp.google.com
