v16.21 private server update, all borders are red

[DoogenAC 0]

I've been running a 3x2 for weeks now. This evening I was being prompted to apply MS patches (Win10). So I performed a clean Atlas shut down of by my physical servers.

And reset both.

And applied Patch via Steamcmd (with multiple verifies).

Now my borders are red and impassable.  I can fast travel between zones. 

 

Any thoughts on what could cause this?

hmm applying second round of Microsoft updates (cumulative update) seems to have returned Atlas things to normal. I may never solve that one. ah well.
