Which is why over-subscriptions are common.  In conversations about Cogent,
others have indicated to me that 2% packet loss is pretty common and
unacceptable and given as the primary reason for not using Cogent for a main
pipe.  Price isn't everything.

I note one wireless ISP (www.pathbroadband.com) that has moved from Cogent
to Level3 recently.  Don't know if performance or financials were factors.
