Steam Community down?

Works good for me.
Also....

I'm getting a ping timeout so it's not just you.

Same here, doesnt work (or is very very very slow)

For some

It happens several times a week, and every time there's a post about it. Just give it some time.

I'm having SERIOUS issues. It's not Steam Community, it's Steam.

This thing is misbehaving badly: cdn-87-248-217-254.frf.llnw.net

Any attempt to access something on Steam results in a never-ending loop of network accesses to the above server, which grinds my browsers and my whole internet to a halt, reminiscent of the days of 2400 bps modems.

Well that Steam Family Sharing is being rolled out for the first 1000 people who joined the Steam group today. Probably has to do something with it being a mess right now.
