Considering that this is a direct cross connect from Leve3's cage to my my
cage in the same DC at an Equinix facility, 100Mb DIA w/EIPT VoIP service, I
would expect nearly 100% success.

Considering the circuit was just turned up and there is no data except
Level3's phone traffic.  They are our carrier, RespOrg, origination and
termination, no 3rd parties, all on net.

I could understand if it was a peaked out DIA circuit to some cut rate VoIP
provider, but not under "perfect" circumstances.

Thanks,
Steve Totaro
