Nebula (nodenebula.com) is back to OK after about 25 hours in an error state. Swap success rate is still low though — 3 out of 10 — so it may not be fully healthy yet. This mint has been flipping between OK and ERROR pretty regularly over the past few weeks. Not a one-off blip at this point — more of a chronic pattern. Something to keep in mind if you're using it.
