It looks like snowflake-broker.azureedge.net has stopped resolving (meek-reflect.azureedge.net as well). I don't know exactly when they stopped working. According to the 2025-01-30 team meeting notes (https://lists.torproject.org/mailman3/hyperkitty/list/tor-project@lists.torp...), it was still working on that day.

$ dig snowflake-broker.azureedge.net @1.1.1.1

P.S. I checked the billing graph to try to find when it stopped working, but the graph stops showing charges after 2025-01-16. We know it was working for a while after that.
