Difficulty nose dive, wtf

Got a full time node and have been making a thing of archiving the difficulty count every so often.

Earlier tonight, when checking current difficulty, first thing of notice was that it had dropped to 8000, so immediately logging was enabled.
In a matter of for what it seemed seconds, it had then rose back to 15000+ and continued to ascend:

15693,Sat Nov 5 19:39:00 2016 CST
16715,Sat Nov 5 19:39:10 2016 CST
16059,Sat Nov 5 19:39:21 2016 CST
17768,Sat Nov 5 19:39:31 2016 CST
21003,Sat Nov 5 19:39:41 2016 CST
23014,Sat Nov 5 19:39:51 2016 CST
...

If anyone has any logs of their own from around that time, would be interested to see if anyone caught this.

Something wrong with your node.
