Update: Oops, I meant TTL.. not ARP :D
The reason being is most users connect to Facebook or Instagram DAILY... which means their TTL cache would still be applied...
This happened either several days ago and users are just now starting to be affected as TTL cache expires... or something more deep. Actual routing problems.
This could be the start of the take down and the 10 days.. I hope all of us are prepared if so.
You are right... ARP caches the mac address. Brain fart.... I mean't TTL... DNS propagation time..
I gotchu... posted a top-level comment with some findings, you got the snarky answer because I was mid-dig and confirming what I was seeing with a few of my peers.
No worries! I want to be corrected when I write something that is incorrect, even if it is a sarcastic or snarky correction
Also, I didn't take your correction as snarky at all :)
