I lost ipv6 at some point today

Yep seeing this too:

Mon Mar 18 11:25:11 NZDT 2019: IPv6 dropped. Running resetv6.sh on router

Hi All,

The team investigated this early this morning, here's a snippet from our notes.

Assessment/Action:

- Noted some users reporting v6 issue again yesterday, including Michael. Found that there had been a commit on WLG-CTR where he is terminated, so gathered a list of all static users on WLG-CTR and checked the routes and route ages for all of them. Found that all users on Fritzbox were fine, v6 route solid since our implemented workaround on Friday. 

We noticed that there was some odd behaviour from some Ubiquity and a Sonicwall CPE devices, however there were some Ubiquity devices that weren't affected (different firmware/config?). michaelmurfy - Are you able to do some testing/look at your v6 config to see if we can get to a working model :-)

Nick.

I'm not saying there isn't an issue with the EdgeRouter, but the same config I'm running was 100% stable prior to your BNG upgrades

@NickMack Excellent. Thanks! There is a known problem with IPv6 with my firmware revision so I am going to put it down to that. Just seems that EdgeOS is a little more sensitive to any changes than the Fritz!Box.

@dfnt I think this is pre-BNG stability. The problem is with EdgeOS. Take a look at the numerous IPv6 threads on the EdgeOS beta forums. At-least now it is not happening multiple times per day... My last IPv6 outage was almost a month ago.

I'm going to lock this marking it as resolved.
