This is the take-away message for me.  Buying transit from Tier 1 (and 
especially almost-Tier 1) providers is a risky idea for single-homed 
customers.  Tier 1 connectivity could be cheaper, and could be 
better-performing, but has this potential for severe connectivity issues.

Single-homed end users would be well-advised to buy transit from a 
multi-homed tier 2/3 ISP.  Single-homed SPs (such as Sprint Wireless, for 
example) should become multi-homed or buy transit from such a multi-homed 
tier 2/3 ISP as well.
