# Correction: check_webfinger!

Mastodon is not the fediverse and in my check_webfinger! post, I’m afraid I made that assumption. In particular, I concluded

So, from the perspective of mastodon, the domain component of your identifier you are known as is determined by which domain serves your actor document rather than the domain serving the original “well known” webfinger document.

which is not necessarily true if you consider the fediverse outside of Mastodon.

Instead, it seems that I should have said that the domain component of your identifier is determined by the domain component of the subject field returned in the webfinger response from the domain that serves your actor document when mastodon makes its 2nd webfinger request which is done in the check_webfinger! method.
