Comment:

 `{{unknown}}` responses indicate something went wrong when retrieving the
 oEmbed, like a tweet that has been deleted or hitting a rate limit (not
 clear on whether Twitter specifically still has one). oEmbed caching only
 re-requests embeds a day past the time in the `oembed_time` key (unless
 the `oembed_ttl` value has been filtered), and does not replace stored
 values with `{{unknown}}`. Do you have a plugin or other code that could
 be affecting oEmbeds or even post meta? We do not clear them en masse in
 any situation in core as of 4.0, and even then, it was only for a given
 post on post save, not globally on upgrades.
