Hi!
Sure, I'm just not sure why you would think that Alwyzon.com runs on one
Nameserver? There are two nameservers, ns1.alwyzon.net and ns3.alwyzon.net (for
historical reasons, there is no longer a ns2). Both have IPv4 addresses
assigned and run in geographically separate locations (Austria and the
Netherlands):

Btw. your mail setup seems a bit off: the email has a "Reply-To: Debian Mirror
Team <989...@debian.org>" header set, but that address doesn't seem to exist. I
got a "550 unroutable address" from "mailly.debian.org[82.195.75.114]". If you
are receiving this mail, I assume it should be "989...@bugs.debian.org" (just a
guess as that was the sender domain used for the system notifications and used
by your mail as Cc).

Can you tell us a bit more about your DNS setup?
It seems alwyzon.com only has a single IPv4 nameserver, and both
nameservers share the same IPv6 address. How does the dns service for
this domain provide availability against spof?
Cheers,
