It does, thanks for the reply. When you say 70%, should we not be spiking that high during business hours? All of our activity is during the day, the T1's are basically empty at night, maybe some Microsoft and Anti-virus updates. During the day I have seen spikes as high as 2.9 out of 3.0. I am going to talk to our ISP to get more detailed reports and get some averages for data in/out during business hours.

For instance, look for streaming audio/video, possible spyware issues, etc. When I first got here, my supervisor was certain we needed to up our bandwidth, based on a monthly report she was getting from our ISP. What I did was request a more granular report, a weekly, and saw that the spikes were happening in the middle of the night, but during the day, we were well below 70% usage. We use an offsite backup solution, and the spikes were the backups running each night. Hope this helps, Joe Heaton From: Chris Blair [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 08, 2008 7:01 AM To: NT System Admin Issues Subject: Bandwidth We are suspecting we need to increase of our current bandwidth. We are now accessing applications over a VPN tunnel and have added more users over the past few months. Application and Internet usage can get slow during the day. We subscribed to our ISP's bandwidth monitoring reports and I can now view hourly, daily, weekly and monthly bar graphs of our usage. So now that I have these reports, my problem is interpreting them. My Googling is failing me this morning. How much usage is too much? If we are spiking up to 2.5m out of 3.0m, is that OK? What is OK? We are running 2 T-1's that are bonded . Yesterday we Averaged 123.4k in max 1.1m and 0.4m out max 1.8m. Is this good, bad?
