Regional slowdowns may happen at times. This is just the thing with a CDN―content delivery network, a system that propagates a site to regional servers to speed up load and reduce latency for people who are physically located far apart from where the site is actually hosted―and it may only impact a certain region at a certain time when it's smooth and snappy for everyone else. Browsing the site from North America, I haven't been experiencing any slowdowns as of late, including from before this thread was made.
Nevertheless, we hear you, and we've been continuously working on improving our infrastructure which will in turn make loading the site smooth as a breeze for everyone and minimise downtime as much as possible if not downright eliminate it.
