My question is, is it reasonable to assume that a DDOS attack against one customer in a data center can have repercussions for other customers?
Without knowing HOW the infrastructure in the data center is setup, it's hard to answer this question.
If there's shared infrastruture, then yes, it can -- typically'd it'd start with the pipe coming into the
data center that said customer (and everyone else) is coming in / going out of.
