The default alternatives are LA, New York, London, Paris, Kyiv, Beijing, and Tokyo.

Cheers for that, your comment reminded me to check.

They're regional defaults - I'm getting Adelaide and Sydney thrown in as I'm in Australia .. and a few Asian cities also, along with London etc.

It's close but not quite my Timeanddate customs - I specifically use Toronto for the TSX time.

I guess they're not looking for competitors cookies after all :).

It’s also not possible for them to read the cookies of other domains without those domains setting cookie access control that explicitly allows it.

That's something I 'knew' in theory .. but as I'm back end numerical geophysics coder that avoids web UI as much as possible I frequently lag on the latest sneaky end runs in practice.

Nice to know that this is still the case - but always worth checking.

Yeah, the security of the web depends on it so it’s unlikely to ever change.

Your session tokens that give you access to a website after you’ve logged in are stored in those cookies. If another site could read them, they could use them to access your email, etc.

Why no UTC? I guess London may be the same, though I’m unsure about DST?

The launch wasn’t listed in UTC but in its local timezone? That is odd.
