TCEC S16 L1 Finished; CCC10 S1 in Trouble

Another Monday, another report on the two ongoing engine-vs-engine competitions. Last week, in TCEC S16 L1 Wrapping Up; CCC10 S1 Underway, I noted,

TCEC: 'League 1' is almost finished. • CCC: The first stage, 'CCC10 Qualification', is already more than one-third completed and should finish this week.

Since 'almost finished' and 'should finish' are only forecasts, what's the current status of the two events?

TCEC: After 'League 1' finished, the top four engines participated in a playoff to determine which two engines would advance to the Premier Division (aka 'DivP'). The two AI/NN engines, Stoofvlees and ScorpioNN, finished 1st/2nd in the playoff. The results of both events are shown in the following chart.

TCEC admins are currently testing a new server:-

TCEC webserver has proven to not have been stable always. Therefore we are currently configuring a completely new webserver, and will continue with DivP when ready, which should be within a day (at most). This new webserver will eventually completely replace the old one.

The Premier Division will run for about three weeks.

CCC: Last week's forecast -- 'CCC10 Qualification should finish this week' -- ran into some kind of a brick wall. All non-AI/NN engines have finished playing against each other, while the four AI/NN engines are currently completing their schedules. During the past week, the CCC ran a 'Sanity Test GPU Server' with those same four engines. I couldn't find a discussion of the problem.
