Actually, the bug was in OpenSSL so those web servers may just be the
highest profile, but not the only, software affected...

It's trivial to exploit and undetectable without a network level packet capture.
Who or what was exploited is one of those "known unknowns" so everyone
should just follow the recommended course of actions:
- patch the software
- regenerate new keys
- create new certificates and revoke the old ones
- revoke existing access tokens, session cookies etc.etc
- trigger password resets
This may seem like overkill but it's realistically the only way to restore a
semblance of security and is not overly onerous given the alternative
possibilities.

The only issue I have with this is it only checks the *current* status of
the bug itself. It should also be checking the issue date of the certificate
and warning that if it was not generated recently with a new key *and* the
server was previously vulnerable then the server may still be at risk due to
any previously retrieved key material or access tokens.
