Although we have nothing to do with it, we understand it as a first in , first out. So if we scale the work, we figure it will take about 1183 days! :) HEHE JK!
But, lets do the math.
You are last in line
.05% of users are having the same issue
There are 1.5 billion Facebook users
Workers work 24/7.
on any one 24 hour shift, 50 workers clear the pool.
it takes 20 minutes to clear any 1 issue.
How long does it take?
