However, when I would get one quickly, it was WAY too quick, in the > DiG 9.11.4-P2-RedHat-9.11.4-9.P2.el7 > +trace I was seeing traceroutes to the root name servers in the realm of 20-40ms but I was getting DNS query responses back anywhere from 3 seconds to never. Started doing more digging and doing timing tests. v/tMTMhCpk16kk2iM6ckfFftGalf7yKrrgmOHZkWPIUA97vfkR0YqRtPOzXe8wy9GxR7OXMUKweqfHpgmK/tduGh3a8qdaZ69rFI+bhARgg8r+2TnsLDMgGaJL1s3VvjF10l4pKJ7NILeXz1BtoowxHh9u4ug2Z5SWVGp+NLdXpVjWNFtk3HJlyFYftFoeFJpN+W7yisfNQ3M/zj5Mn/qjFz00dh+1B2aFicUiOErlSV3LuHvKi5dMji1pCnDSkB/nMnRcOXC844G2WWt401p8eSBJ3Ycz3HO+f881PJbxo0QJQ/CH91z09yUPn/LShvZz1NIWt+XAYfaOPz v6ksKA=
What I found was queries to root name servers were returning IP addresses. I started doing more testing from one of our web servers that hosts a recursive DNS server for looking up RBLs and such (since they rate limit using public name servers usually results in some sort of a block). When I switched some systems over to DNS over TLS and redirecting to 1.1.1.1 / 1.0.0.1 the issue would go away. On Mar 17th I started noticing a huge number of outbound DNS queries taking a LONG time to return, I started doing some digging. There's no place to configure it and it's not real clear what it is based on any literature I could find. I have no idea what it is or what it does.

About 3 weeks ago I did a speed upgrade on my Xfinity Business line and they threw in SecurityEdge for Business as part of the package.
