Update 4:33 pm PT: It looks like the "too many requests" error has cleared up, and the Steam store is loading again. SteamStat.us shows that the website servers are still down in Dubai, however. Everybody else should be able to load the site now.
It's not just you: Steam is down right now. If this were a Tuesday around this time that'd be no big deal (Valve does maintenance every week), but on a Thursday, you have good reason to be looking for an explanation for the error that currently displays when you try to load Steampowered.com:
"You've made too many requests recently. Please wait and try your request again later."
No, you're not being blocked from Steam for reloading the store too many times. Something's wrong: SteamStat.us reports "too many requests" errors for both the Steam store and Steam community. Maybe something to do with the Summer Sale ending today?
Many of Steam's services are still showing a green light, and we're able to see friends online. Steam's matchmaking services are likewise still in operation, according to the status page. It's specifically the Steam website that's out of commission. We'll update this post as the situation develops.
