Hi, Michael Altfield here (Founder of the BusKill project and holder of the PGP Key for signing canaries)
No, you should not be concerned. The latest canary #002 literally says:
Period: 2021-06-01 to 2021-12-31
Expiry: 2022-01-31
What matters is what's cryptographically signed. Did I make a mistake somewhere else?
The next canary will be posted before 2022-01-31.
