What is sticky egress?
Sticky egress keys the exit address on the run’s account label (or an explicit session key) rather than picking a fresh one each time. Its opposite is per-request rotation, which is the correct posture for anonymous reads and the wrong one for anything tied to a login.
Why it matters
An account that signs in from a different country on every request is a pattern no real user produces. Stickiness and rotation are genuinely opposite stances, and setting both is the common configuration error that undoes the identity you were protecting.
