OK, that's good news.

But if you yum update, you're still not able to resolve?

It sure smells like a DNS issue to me, but both the nameservers for 
blueonyx.it are functional:

# nslookup
 > server ns1.solarspeed.net
Default server: ns1.solarspeed.net
Address: 208.77.221.200#53
 > updates.blueonyx.it
Server:         ns1.solarspeed.net
Address:        208.77.221.200#53

Name:   updates.blueonyx.it
Address: 38.114.102.5
 > server ns2.solarspeed.net
Default server: ns2.solarspeed.net
Address: 208.67.251.185#53
 > updates.blueonyx.it
Server:         ns2.solarspeed.net
Address:        208.67.251.185#53

Name:   updates.blueonyx.it
Address: 38.114.102.5


FWIW, those nameservers are on different systems.  An temporary outage 
at one of them should not cause any issues.

What nameservers are you using for your recursive?  Are they ones 
provided by your datacenter / ISP?
