Where are Helius's RPC nodes located?

I want to set up my server close to one of the nodes so that I can reduce latency. Where are the nodes located?

Helius provides services through a globally dispersed set of nodes, strategically positioned in key locations: New York, Ashburn, Chicago, Vancouver, Los Angeles, Singapore, Tokyo, Frankfurt, and the UK.
Helius automatically directs user requests to the closest node, guaranteeing the quickest and most efficient routing.


Are any of these AWS instances so I can try to locate on the same one?
