Web page takes minutes to resolve at peak times
Good Morning all,
I've got a bit of a problem with internet speed only at peak usage times around the school, we are experiencing an odd slow down issue, website addresses take around 3 minutes to resolve in multiple different browsers (IE Firefox Chrome) but once they resolve they are downloaded in milliseconds. We have a fast connection speed (fibre 100mb) and 1Gb internal network speeds two DNS servers running 2008 and forwarders with google top of the list. smoothwall filtering and a Cisco ASA box.
Does anyone have any other possible ideas? would DNS Server loading be an issue?
thanks in advance!
(oh and peak usage is around 80 users!)
