We had a VERY similar situation with 2 of our coloc. raq3's.
After much tinkering and diagnosing,  it was found to be a faulty router, 
but there was no way the coloc. company would admit any problems their end!

If the problem extends to both raq's then a routing problem could be the 
cause. However, if the problem clears when the network admin tinkers with 
the firewall then???

If the problem persists perhaps you could post your dns records/setup, then 
it could be looked into further.
