On my side, connection to http://sagecell.sagemath.org
times out. Requests to sagecell.sagemath.org are sent to several different servers, depending on where you connect from. There are servers in two universities in Spain and Germany (I imagine all Europe requests are routed there) and one server at Google Compute Engine (I imagine all North America requests are routed there). See https://wiki.sagemath.org/Infrastructure I don't know if you can bypass the routing algorithm and decide to connect to a given sagecell server. Your workaround for now is that the aleph.sagemath.org server seems to be working for all. Samuel -- You received this message because you are subscribed to the Google Groups "sage-support" group.
