My change was in a different datacenter.
Roll that back.
I changed the internal network and this is an external problem.
Please be rolling that back.
I only changed staging.
Oh really? Roll it back.
My change couldn't possibly be related!
Don't care, roll it back.
I didn't change code, it's just a backfill
Don't care, roll it back. Turn off the backfill.
Nothing changed! I just added some additional app nodes!
Turn them off.
Seriously it would be impossible for this change to be related.
You keep using that word, I do not think it means what you think it means. Roll it back.
