Although both 13.35.20.0/24 and 52.85.158.0/24 IP ranges are located at Seattle,
the result shows that the connection to 13.35.20.0/24 is significantly faster.
This is pretty normal in China. It's definitely caused by the GFW. Giant
internet service providers (e.g. AWS) are the primary targets of the GFW.
