FAA.gov nameserver outage

Looks like faa.gov's nameservers are all having a bad time, only occasionally responding right now from multiple tests from my home network, datacenter POPs (Seattle, Chicago), and 8.8.8.8 -- "Genius might be described as a supreme capacity for getting its possessors into trouble of all kinds." -- Samuel Butler

I don't know how one would contact them, but the list of the senior IT officers are on their memorandum to migrate to IPv6 dated September 2021. This memo states they would be migrating in 2023.

What would be the symptoms here of a "water torture attack" rather than what John had indicated as a firewall failure in their infrastructure:
Initial looks from the firewall team point to an automatic failover event and the secondary failed.
And the symptoms of which lined up with network level info from Paul earlier:

Are you saying that your open resolvers have a per client rate limit applied, that rate limit got tripped, and shortly thereafter the resolvers became unavailable, suggesting query floods for the domain(s) that knocked the resolvers offline (or from the other discussion, possibly was the thing that overwhelmed that firewall layer, causing the initial failover and possibly also causing the firewall secondary to fail to come online)?

Yes. (limitting per client, and per second for all) Perhaps, large numbers open resolvers including no ratelimit are used. Then massive random subdomain queries caused the firewall symptoms. (It's only my guess.)

Are you saying that your open resolvers have a per client rate limit applied, that rate limit got tripped, and shortly thereafter the resolvers became unavailable, suggesting query floods for the domain(s) that knocked the resolvers offline (or from the other discussion, possibly was the thing that overwhelmed that firewall layer, causing the initial failover and possibly also causing the firewall secondary to fail to come online)?
Yes. (limitting per client, and per second for all) Perhaps, large numbers open resolvers including no ratelimit are used. Then massive random subdomain queries caused the firewall symptoms. (It's only my guess.)

What would be the symptoms here of a "water torture attack" rather than what John had indicated as a firewall failure in their infrastructure:
Initial looks from the firewall team point to an automatic failover event and the secondary failed.
And the symptoms of which lined up with network level info from Paul earlier:
They only seem to have two auth nameservers for faa, both within the faa.gov domain. Don't seem to be anycasted and the 2 v4 and 2 v6 blocks the servers are in all die just within each block run by the FAA.
Seems like an internal routing meltdown making the only 2 nameservers unreachable reliably.
Are you saying that your open resolvers have a per client rate limit applied, that rate limit got tripped, and shortly thereafter the resolvers became unavailable, suggesting query floods for the domain(s) that knocked the resolvers offline (or from the other discussion, possibly was the thing that overwhelmed that firewall layer, causing the initial failover and possibly also causing the firewall secondary to fail to come online)?
Yes. (limitting per client, and per second for all) Perhaps, large numbers open resolvers including no ratelimit are used. Then massive random subdomain queries caused the firewall symptoms. (It's only my guess.)

It loos like random subdomain attacks (water tourtue attack).
