 Is this machine by any chance running in a VM on a shared host? It could
 be due to the hosting provider de-prioritizing our VM if so.

 I suppose a good next step is to try to narrow down whether this is a
 network issue, but we can't do much until the symptoms start up again. My
 current plan is to wait for sysmon notifications and then run something
 using `time` to see if it's taking a lot longer than usual.

 It might be the case that the issues weren't showing when you did the
 download. I don't have any alerts since the 1st of September so we should
 try that again when we're sure the broker is acting up.
