File server domain is sharded into multiple subdomains, but is2.4chan.org is slow.
Replacing it with i.4cdn.org can speed it up.

The following one-liner does that

> $.qsa('a[href^="//is2.4chan.org"]').forEach((a) => { a.href = a.href.replace('is2.4chan.org', 'i.4cdn.org'); })

I don't know what's causing this though.
