This could be an NNI or peering disconnect between light tower and Level3.  Light tower has been doing maintenance on different nodes... They have been know to forget to notify their peers .

Today my users are complaining about slow database response, and I find that traceroutes from here, and from Level3's Looking Glass Boston page now go from NYC to Poughkeepsie via Washington, Atlanta, and Miami. This is a new routing; traces from past months went directly from NYC to Poughkeepsie.
