DNS wierdness and cox communications

[Ryan Rix]

Hi Mr. Hawke,

I've been recently (as in today as of about 10am, judging by kopete disconnect 
logs) having many DNS issues quite along those lines (certain pages return 
dns lookup failed)... But, strangely, I use Qwest...
Not to be creating dumb ideas, but I wonder if these are interrelated?

*I can't connect to support.dlink.com (to check if my router's firmware is in 
need of upgrade and other support help)
*I can't connect to messenger.hotmail.com or any hotmail.com subdomains (the 
origin of all my issues, MSN messenger refusing to disconnect, kopete telling 
me my "connection actively refused" which according to google can be either a 
server or ISP drop. traceroute says my packets make it to hotmail's servers 
but I don't trust that given my dns lookups to it fail... :P)
*I can't connect to skype, though my contacts appear online, I can't IM or 
Voice chat.

So I see basically the same thing happening, only on Qwest.

My nameservers are:
205.171.3.65
205.171.2.65

both of which resolve to resolver.qwest.net and follow the guidelines posted 
here: http://www.qwest.net/help/roaming.html

Not to be a conspiracy nut, but perhaps these issues are related? No one else 
I know (only Cox subscribers IMO) in the Phoenix area are having any issues.
