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.
