Re: cdn.d.n needs update for debian.ethz.ch IP switch / cdn.d.n health check broken?



Hi, I'm sorry. Late reply.

I will investigate soon. Please wait.

JFTR: This doesn't necessarily relate: I've just got a DNS reply
pointing to my old server:

$ host cdn.debian.net
cdn.debian.net is an alias for deb.cdn.araki.net.
deb.cdn.araki.net has address 129.132.86.210

And then again a few seconds later, pointing again to Germany and
BiH and then again to Portugal and BiH:

$ host cdn.debian.net
cdn.debian.net is an alias for deb.cdn.araki.net.
deb.cdn.araki.net has address 137.226.34.42
deb.cdn.araki.net has address 195.222.33.229
$ host cdn.debian.net
cdn.debian.net is an alias for deb.cdn.araki.net.
deb.cdn.araki.net has address 193.136.216.34
deb.cdn.araki.net has address 195.222.33.229

Looks more like a DNS round robin currently (which is not what I'd
expect when querying from a host in the same AS as the (old and new)
mirror server.
