Yes; actively being worked on; Juniper T1600 went kablooie, and when it went away, anycasted DNS went haywire as well; still digging into it more; yes, this is primarily affecting traffic coming through Ashburn, VA. No, I don't have an answer on specifically what happened; yes, we're aware of the issue and have put workarounds in place; you should be back up and functional for the moment, though not in an optimal state. Matt And no, I'm not speaking authoritatively for anything or anyone at the moment, so treat this with a few grains of salt.
