I also just noticed that my number of peers dropped to 10 (including my farmer and wallet). Although, none of those is blocked. I am both getting and sending data to those peers. I also don’t see stales, so this behavior looks like a new one.
Is that another form of dust storm? If that is CAT1 related, then based on what Chia said, there are only few key nodes running v1.2.8/9, so that would be just a drop in the bucket.
