I have looked at the domain NS and it seems that 2 out of 4 are not
responsive at all.
If you are interested in clearing out the issue and more advanced dns
related issues you can try bind-users@xxxxxxxxxxxxx list.
In the above list there are many dns administrators that can help and
consult you on the next step to make the issue one of two:
- gone(fixed locally)
- fixed(fixed by the ns servers admins)

Hello.
Some of our user are complaning about very slow access to some sites.
After some tests i've noticed that the time between squid receiving the request, and actually connecting to the site itself is very high. After this wait all the objects in the page are fetch rather quickly.
I've tried upgrading to 3.4 but the issue persists. No auth in place, and the Squid server is connected to internet via full nat.
Connecting directly from the server ou via some other proxy software, like nginx, works perfectly.
Here are some of the sites (this are portuguese insurance companies):
www.nseguros.pt
www.lusitania.pt
www.logo.pt
Any ideas?
Thanks in advance.
