We have been having problems recently showing up with the TC chassis. We are using the HiPerARC and DSP with channelized T1s. The software version is

ARC 4.1.59-6 and DSP 1.2.37 and testing 2.0.60 on some DSP cards. Customers are beginning to complain about web pages are timing out from more than one POP site. Strange thing is nothing has been changed on the chassis except the radius server. Checked the configs but nothings seems different. Anyone have any idea what could be the problem? Any ideas are appreciated.
