Sudden reduction in snowflake-01 bridge bandwidth, 2022-10-04 17:15

At around 2022-10-04 17:15 (about 2.75 hours ago), bandwidth on the bridge suddenly dropped from about 3.2/2.4 Gbps TX/RX to about 1.0/0.8 Gbps TX/RX.

There is normally a nightly drop in usage, but this drop is several hours too early for that. It's also unusually flat.
