Steam not working?

well at one point i logged off steam to play a quick MMO for a bit to take a break from the constant download for L4D2.
tried logging back on like 2 hours later and now it keeps giving me an error message ...

"Could Not connect to steam network
This could be due to a problem with your internet connection, or with the steam network. Please visit Welcome to Steam "

whats up with that? .... and better yet ... is there a way to fix it? (provided its not them doing some sort of maintanence) according to Down for everyone or just me? its up. so its really throwing me off a bit ...

(its been offline for me about 2 hours ... maybe 3?)

Quick Note: Web browsing steam with IE8, Firefox, or Google Chrome doesnt work for me either.

its works for me. maby they just went down for a bit

Worked for me last night.
