I appreciate the reply, I don't follow your logic though sorry. You think my issue is probably DNS related? I tried to do my best to illustrate that it is not. I gave examples that under my 2.6 builds this issue does not occur, and from my 3.2 box a nslookup and dig return the record instantly. I even gave logs from the 3.2 box showing that it can't resolve the name however it is trying, then 30 seconds later it is able to.

This morning I even went one step further isolating this issue to it being something specific to Squid 3.1 or 3.2. The box I showed my results for that is 3.2(Cent OS 6.4 64bit), I uninstalled 3.2 and I downloaded and compiled Squid 2.6 this morning and it is NOT having this issue at all. (Which BTW this is 3.2.9 I have been referring to)

So now that I have confirmed that compiling 2.6 on the SAME box that 3.2 has this issue, can someone please help me out here and point me in the direction to finding a way to resolve this? Should I submit a bug report for this? This is the first time I have ever run into an issue with Squid before that I could not resolve.

I turned on debug with 2.6 and in the cache.log it does NOT report the same lookuphostip errors that 3.2.9 does when resolving The 3.2 logs show the error in when it fails, does anyone know anything I can try to hack to get this to respond quicker than 30 seconds that it currently does? I assume this is only occurring because of the DNS recursion going on with this specific host. All other sites I hit on the 3.2.9 box come up instantly because they all resolve right away..

I would really like to move on from the 2.x and take advantage of how much better the newer version supposedly scale.

Thanks again.
