According to DOE's 3:00Pm Report, Colonial Pipeline (Texas to New York) is now operating at reduced rates. This may be greatly reduced rates--the report doesn't give enough information to tell. The other information still seems to be correct.

It would be of interest to know what the entry points are for the Colonial and other pipelines. Which refineries can supply it?

For a good treatise on the US pipeline network and how it functions, read this document:

Their Networks, Operation and Regulation

It dates to 2001, but it doesn't give many specifics anyway.
