A few weeks ago there a blip in the Chia Network caused by Bluebox timelords compressing too many blocks and overloading some full nodes. After that event Chia turned them off, released version 1.2.6 and promised in an AMA to let us know when they were going to turn them on again.
Well, they are doing so. So if you haven’t updated to Chia 1.2.6 yet you should head over and update to 1.2.7 to ensure you don’t see any disruption from the blockchain compression.
