It appears we had an “invalid block”. Our server was not offline at all (we monitor it constantly), the KES is valid (until 2022), it was minting blocks this epoch without problems. So this is unexpected.
The next block was fine. So it’s definitely not a KES issue. We have 6 relays, and they’re all well-connected. We did everything perfectly, so WTF?
Has this happened to anyone else? We’re using node version 1.31.0.
Does anyone know what might have caused it?
