@nora_js
“We ran a chaos experiment which
verifies that our fallback path works
(crucial for our availability) and it
successfully caught a issue in the
fallback path and the issue was
resolved before it resulted in any
availability incident!”

21.
“While [failing calls] we discovered an increase in
license requests for the experiment cluster even
though fallbacks were all successful. This likely
means that whoever was consuming the fallback
was retrying the call, causing an increase in
license requests.”
