Alas, the joy of multihop BGP.  :)  This is why we recommend at least
two peering sessions to two disparate route-servers.  We'll take the
same approach with the expanded IPv4 and IPv6 offerings.

If you could send me a list of outages with dates and times, I'll look
into those ASAP.  I can see if other sessions were dropping at the same
time, upstream outages, etc.

Feel free to hit up noc at with outage reports as they occur as well.
