OT: When to upgrade bandwidth?

Hi Experts,

Is there a golden rule as to when an organization should do bandwidth
upgrade? We have a few T1s that we use for different purposes and on one of
them I have seen increased utilization and often the connection is slow (to
the internet). I am using netflow, Netflow analyzer Pro to collect the data.

How many "Ws" should I see in the graphs consistently before considering
bandwidth upgrade or move certain services to another T1? How many spikes
into the 95th percentile utilization should there be per day, week, month?

We have 4 (maybe more later) site to site VPNs (to a concentrator) for our
remote locations, about 100 employees all together.

I personally, would like to move the VPNs, etc. to a dedicated T1.

Thanks,

Haroon
