Nick here from Silicondust...

Confirming, we found and fixed a bug in the firmware a few years ago
relating to DNS handling.
For HDHomeRun PRIME units it affects units running 20130117 or older
firmware.
For HDHomeRun DUAL units it affects units running 20141124 or older
firmware.

The easiest fix is to unplug the WAN port of your home router so the old
HDHomeRun firmware is happy, then upgrade it to the latest firmware
(20161107b for PRIME and 20161107 for DUAL).
The direct firmware download links can be found on our website under
Downloads, Linux.

We are beefing up our server infrastructure... we now use CloudFlare for
the first level. Behind that we have caching servers in four locations for
speed, redundancy, and backend failover selection. Finally we have the
backend servers, with most services being served by redundant servers.
Linux and scripted builds all the way through. I had fun setting that up :-)
