They’re starting to pick themselves back up off the floor in the last two or three minutes.  A few answers getting 
out.  I imagine it’ll take a while before things stabilize, though.

aaaand we’re back:

WoodyNet-2:.ssh woody$ dig www.facebook.com @9.9.9.9

So that was, what…  15:50 UTC to 21:05 UTC, more or less…  five hours and fifteen minutes.

That’s a lot of hair burnt all the way to the scalp, and some third-degree burns beyond that.

Maybe they’ll get one or two independent secondary authoritatives, so this doesn’t happen again.  :-)


We have had dns back for a while here but the site is still down. Not counting this as over yet.

Yeah, fair enough.  I went back and looked, and it looks like the BGP withdrawals were around 16:40 UTC?  And as of 
22:15 UTC, application-layer services still aren’t up.  Which puts us at 6:35 thus far?

Arrrr.  It’s past midnight here, and my brain is failing to convert between three timezones accurately.  My apologies.  
I’ll stop typing until I’ve had some sleep.  Good night.
