I wouldn't be so quick to excuse your ISP, perhaps it's your
connection, not their nameservers. Does the mtr program (try it if
you don't know it) show good connectivity to or
(the google public recursive name servers)?

I would focus on using dns query tools for determining dns
availability.  Your browser will say looking up dns after it gets
records and queries the webserver. Been that way always, I don't
know why.

I prefer djb dns tools. But you probably don't have them installed.
You probably do have dig installed, to test a dns server, try:

dig @ google.com

I get best dns performance from a local cache but not everybody
does.  Try http://code.google.com/p/namebench/ to see what works
best for you.

Also, you could have local issues.... for example make sure all
florescent lights near your wires are off, and test with a wired
connection vs wifi.

Good luck!
