We use other runners (Blacksmith), and it hasn't helped, still hard down all day long. Brutal outage.

As a side note, I started getting these symptoms (actions staying queued forever or not running at all) at 5pm PDT yesterday, intermittently. And definitely full outage by 8:30pm PDT. So for sure full outage for 7 hours and counting, even if you use other runners, and I strongly believe partial outage for ~15.5+ hrs before that, even if it hasn't been acknowledged by GitHub yet.
