Not when I'm the downstream customer, no. It's jolly good that *you* can test, but before the rest of us can get through the layers of support which insulate you, we have to be able to convincingly test too. > As I know 100% of ISPs (to at least one decimal place) cannot > make such a guarantee, then doing so puts the IXP and all other > members - whether peers of yours or not - at risk.

The IXP is at no more or less risk from your customers than any other connection you have for Internet carriage. Risk which you are responsible for managing either way. > I said in an earlier post that if you carry a prefix I own, > did not announce to you, and make it very clear I > specifically do not want you to carry, I will ask you to > stop or face possible disconnection.

I respectfully question the wisdom of such a rule and the IXPs I deal with only ask that you not announce the IXP prefix externally. But it's not OK to unilaterally break the IXP's rules, however poorly conceived. Regards, Bill Herrin -- William D.
