I've had nothing but troubles with Google Search. They keep emailing me to tell me I have problems and they won't index my pages. When I look at the specifics, it's clear they're looking at the last version of my page that was hosted by Google Sites and are ignoring the current version hosted on a mix of GitHub and CloudFront. Even after deleting my Google Sites sites 8 years ago, they're still refusing to look at anything other than the stale cache they keep around for unknown reasons.

I think it boils down to "you're not Amazon or Facebook or the NYT, we don't care."
