 > Ideally, we would only collect stats from the broker that people are
 actually using, which right now is the old broker which the freehaven.net
 snowflake domains point to.

 be to point CollecTor to `snowflake-broker at freehaven.net` now and replace
 the metrics files from 2019-10-16 onwards with files from that host?

 I just updated CollecTor to point to `snowflake-broker.freehaven.net`
 which means that the new files should show up in a bit.

 The next step would be to delete files we don't need in the archives
 anymore. I'd list them here first before deleting them. I'll do that later
 today or on Monday.

 > When we finally move the freehaven.net domain to point to the new
 broker, we just need to make sure we don't overwrite these old files again
 (or we could copy over the metrics files to the new host when we do the
 switch).

 I'm not sure I understand what's needed here. Does this require any action
 on the CollecTor side? If so, can you elaborate?
