Hi Brian,
Hi,
But what's exactly at 2a03:2880:f012:3:face:b00c:0:1?
It's one of the endpoints involved in Facebook's Messenger service. IIRC it's "graph.facebook.com", although I note that that address is currently answering as:
graph.facebook.com. 2068 IN CNAME api.facebook.com. api.facebook.com. 2068 IN CNAME star.c10r.facebook.com. star.c10r.facebook.com. 25 IN AAAA 2a03:2880:f00e:a:face:b00c:0:2
To be fair though, that one could just be what a load-balancing name service is responding at the moment. Notice that the two addresses are only off by one.
But even more interesting is that it's now working:

And even just a few minutes ago it was not as I was testing it for another (off-list) query:

Perhaps the bit of cage rattling that I have done here has knocked something loose. :-)
Cheers, b.
I think TFBNW folks definitely read these lists, even if they never respond officially. Their whole network was apparently down via IPv6 for like at least a few days several years ago; they've then fixed it back in the day by simply removing the AAAA records. :-) https://puck.nether.net/pipermail/outages/2013-May/005570.html https://puck.nether.net/pipermail/outages/2013-May/005579.html It's kind of amazing that tech reporters never really pick up these stories, TBH. I guess these outages don't really sell, especially if noone but a few selected users can even detect it in the first place, even if they do last for days or even weeks/years for certain users in certain configurations. Cheers, Constantine.
