I wonder if "run your own anycast network as a service" would ever make sense as a product. I can't see anyone other than CDN or testing being terribly interested, and a lot of this is included in the raw CDN use case.

https://rage4.com/Home/ANY Is that what you are looking for? They only have 3 locations tho.

Looks a bit like a one person shop – not exactly what you're looking for while building a high availability system.

Please do not run your own DNS server if you do not have the knowledge or expertise to properly secure it. It is extremely irresponsible, and the article is also irresponsible for suggesting it and not having any information about rate limiting.

Use nsd. If you just run an authoritative only service, it is easy to do correctly.

I run a recursing DNS server behind a firewall for my home servers -- is this risky?

Route 53 now does GeoDNS so you can map it more accurately, for a few cents more. http://aws.amazon.com/route53/pricing/

Awesome, didn't realize that! Will definitely be using it.

It just came out this week which is probably why. :)

2 person shop. ;)

That said, some people on lowendtalk swear by them and they usually are the first to complain about not getting 100% uptime on a $7 a year VPS.

Plus your DNS servers (you are running more than one right?) are never going to be as fast as Route 53 and the ilk. Spend the $5/m and use a real DNS host.

This is a neat article, but 'CDN' is such a broad term. This is much more a very well done proof of concept article, but fails to take into account the huge scope of a large scale CDN, and all associated quirks it comes with.

For the record, the setup shown with PowerDNS is authoritative-only too.

The Powerdns geo backend as mentioned by the article is used by wikipedia among others.

I have some additions (e.g. Google Public DNS), see the files at https://gist.github.com/dgl/8344c3ebe405a1400e2d (which also has the rsync location for the original).

[edit: now I read the article again I notice the author is assuming 'eu' is going to get all of EU, it won't. There need to be entries for each country.]
