You can't register a ch domain with fewer than 3 characters. It's showing as available because that thing that checks available only looks if it's registered, not if it's allowed.

Technically they’re used for the Cantons so to register a two letter CH subdomain you first need to register a new Swiss Canton!

Abbreviated internetarchive.ch ?

URLs don't admit abbreviations. "url shorteners" are page redirects.

They are suggesting that a human used an abbreviation rather than making a typo.

Wait was that right in the sibling comment

Oh, so you admit to purposely playing dense by asking if it was a typo, to obliquely make a pedantic argument about phishing?

I hate this fucking website sometimes.

Thanks for trying. I assumed that ia.ch was clearly shorthand for internetarchive.ch but maybe one can't assume anything.

Assumed same.

Good point we shouldn’t abbreviate URLs in case they get typosquatted? Just raised in a very indirect fashion
