SteemIt.com is up but you can not vote. You can use busy.org login in with steemconnect or you can use Steempeak.com if you set your keychain preferences to a Node that is up and working.
The Minnowsupportproject works for sure. I hear Aynx's works as well.
A few days without Steem, it felt like a long time.
OldSteem wasn't happy about it's death and fought back a little harder than anyone expected, hopefully we are moving forward now. :)
What do I do when Steem is down?
Of course, I Tweet about Steem.
Please share your horror stories below regarding how you amused yourself while Steem was down.
Just kidding I'm sure most of you barely knew it was down at all. :)
Have questions about what is working or need help? Come say Hi on:
