RG is just having fun toying with their free users for awhile. Its possible they were tipped off arch-rival Uploaded was about to get killed, so temporarily lifted limitations on free users to snag some disappointed Uploaded folks.
Depending on who posted the file, what forum it is on, and what time of day/evening, I'm suddenly getting 500-900 KB/s on free downloads (also suddenly no 1gb cap on file size).
But more usually I'm getting their typical snail-slow 45 KB/s free service with 1gb file size limitation.
So don't get too dependent on the "new improved" RG - they aren't known for being free-user-friendly. This is probably just a hiccup while they re-structure some things.
