[outages] Cogent /ATT and Verizon Peering alternatives

We are seeing lots of problems with our audio streaming traffic dropping lots of packets where our transit provider Cogent hands off to ATT & Verizon.

Right now, I'm seeing  43% packet loss

Cogent is blaming ATT/Verizon and says there is nothing they can do about it. We're the collateral damage.

Who else is having the same issue?

I threaten to cancel my service, Cogent says, "sorry to lose you as a customer", and go on their merry way.

Are other transit providers having issues peering / getting to ATT/Verizon? I need to know who to avoid.
