2 - Are they pulling CIX peering? (Can that rtr get any more overloaded?
That is just an overloaded SMDS connection, not the router itself.
Last I heard, when the CIX moves locations, AGIS, MCI, UUNET, and Sprint
will all be leaving the CIX.
For those who are not aware:
  --MCI stopped advertising their routes to the CIX router a
    few months ago.
  --Sprint is supposed to have stopped peering with CIX yesterday
    (I haven't verified this yet)
  --UUnet has indicated they will be leaving CIX
These are my observations as a CIX member, not an official
CIX statement.
