Hi, I noticed the initial load time is quite poor... Maybe I had a bad connection but you might want to do some testing on initial load times for your site.
Sorry about this. We only have one server and it is based in Amsterdam. We will try to expand to other continents soon so the load time is fast everywhere.
Getting a 502 Gateway error right now, so can't check the site. However, general advice: run the site through Google's Page Speed checker and see if a CDN + gzip compression etc can improve things to some extent before relocating primary servers.
