Yesterdays rolling update got aborted again, fixed and restarted, caused some concurrency drops and might have influenced the minimum, looking at the steep drop towards midnight. Without that drop minimum concurrency would have been around 32000 as it should have been.
Despite those troubles, today's peak was a Thursday peak concurrency record.

Statistics compared with Thursday, January 24th:
Maximum concurrency grew 1,025 users, a increase of 1.80%.
Minimum concurrency dropped 2718 users, a decline of 8.70%.
Median concurrency dropped 1852 users, a decline of 4.26%.
