I maintain a game wiki that had an extended (~month+) downtime due to hosting issues.

It took about two weeks for us to fall off the first page of google, and our site was far more niche and not well linked throughout the internet than a behemoth like reddit. It's been about six months since we changed hosts, and I still see google try to send people to the old wiki now and then.

Google is trash these days. Now we can add "page indices so old they're growing mold" to the growing list of reasons why.
