I don't know about reading the "new" URL, but to prevent the program from
terminating, you should rescue Net::ProtoRetriableError.  There's probably a
superclass you can rescue as well.  Let me see...

irb(main):001:0> require 'net/http'
true
irb(main):003:0> Net::ProtoRetriableError.ancestors
[Net::ProtoRetriableError, Net::ProtocolError, StandardError, Exception,
Object, Kernel]


Yes, I'd rescue Net::ProtocolError, as in

  begin
    header, data = http.get(URL)
  rescue Net::ProtocolError
    STDERR.puts "HTTP retrieval failed"
  end
