mitigate first, investigate later

• rollback
• scale down / up
• turn off feature flags
• keep looking

a deploy went out, but unlikely related

rollback

turned on a feature flag few hours ago, not likely it

turn it off

error rate isn’t high, not the last deploy

rollback

none of the code paths touched seem suspicious

rollback

scaled up with a config change, its harmless

scale down, rollback

hm, what if its something else

roll back and keep looking
