When I posted original message I see a outage in the BQM about 1am and a shift in latency thereafter.

Stats look fine, I suggest a power cycle, just in case the update didn’t ‘take’ correctly. 

[Timwilky]

I think I have resolved my issue. That software update has kill support for LAGGs on the hub 4.

So now only 80% of what I pay for.

Hub5 needed urgently in order to return to yesterdays performance.
