For some reason a LOT of Microsoft-tagged (whois) IPs are **very** interested in the query "IN ANY fysh.org".

I'm seeing *thousands* of TCP connections to the name server at once, all for that same query.

I'm still going through the list of IPs from about 30 minutes ago, but so far whois is mostly saying "Microsoft", sometimes with a "cloud" tag. There's one bunch of Google in there too, but for all I know they're just because the MSFT ones are causing a lot of:

named[2218860]: Accepting TCP connection failed: quota reached

So, are Microsoft cloud IPs known to do something like this, perhaps some web scraper gone wrong? Or is someone leveraging Azure for some sort of DoS attack ? It's not *incredibly* effective if so, no immediate sign of other issues with fysh.org services, but I've not gotten to checking that in detail yet.
