@gcluley@mastodon.green I would say that the chief being asleep should (and is in this case) be just a PR 'problem'. It's fodder for overexcited newspaper headlines. Operationally it didn't affect the response plan.
DR plans must not assume that an individual can be contactable and there is no tech or process that can guarantee that a person is contactable. Many senior positions would have a deputy with the authority to act if the primary is unavailable.
