Hm… These have come up in the forum before, and the jury’s out about whether they’re really what’s waking the Machine up…
(The Fly.io platform unfortunately has a nonzero number of spurious log lines, which complicates debugging.)
I’m pretty inclined to believe this, but it would probably help to go into more detail about what the exact evidence is… For example, is it Grafana? Your own request logging? The Events
list in the Machine dashboard? Just the fact that you yourself didn’t make any HTTP requests during that interval?
