DNS cannot resolve production.cf.rubygems.org

Hello,

i have a strange problem. i once had (for a proxy test) added "production.cf.rubygems.org" to a static entry with the IP of my internal proxy. Worked. After removing this, the DNS Servers (Forwarders are Google 8.8.8.8 and one of my KabelDeutschland Servers) cannot resolve that anymore (i think its multicast dns entry to amazon cloudfront) but when i do a "nslookup production.cf.rubygems.org 8.8.8.8" on one of my boxes, it resolves correctly to all available cloudfront IPs.

The internal Webadmin->Tools Section cannot resolve it either.

Whts the problem here? Already tried DNS Fixes but DNS works fine for everything except this one.

btw: its latest 9.003-16.

When i try a DNS Lookup on Webadmin->Tools->DNS Lookup the following error occurs:
Host production.cf.rubygems.org not found: 3(NXDOMAIN)

m.

Hi, try checking the IPS log. There may be another log for the DNS resolver as well, but I'm not sure which log it would be.

with DNS Fixes you mean "Flush resolver cache" in Webadmin and "dnsflush" in your computer ?
