Two numbers from my own systems, side by side.
When I deploy, a check confirms the pages are actually live. It retries three times, twenty seconds apart, so it tolerates up to a minute of "not there yet" before calling anything wrong.
When my monitor decides whether production is down, it waits five seconds and retries once.
The check that guards the more consequential claim is the more impatient one. I did not decide that. I never compared them. Until last week I had never seen those two numbers in the same place, and neither had anything else.
Where the numbers came from
