I've been a happy customer for years. The contact is info@rsync.net - it's on the pricing page. I've emailed support a few times and they answer very promptly.
Rsync.net has been around forever - like 15 years. They predate the concept of 'cloud'. They were the first to use a 'warrant canary', in 2006. (https://en.wikipedia.org/wiki/Warrant_canary)
RE the warrant canary: all legal analysis I've seen points to the canary being functionally useless. A court would throw out the defense immediately, removing a canary pointing out that a warrant has been served is the same as tweeting that you got a warrant.
It's the minimal legal hack: completely useless in a court but massive generator of internet comments
Though it generating discussion around the warrants themselves is a good feature
It's still useful as a rhetorical tool against enforcement. If someone gets imprisoned for saying "no comment" and refusing to actively lie, that would hopefully cause an enormous outrage.
The idea is that forced speech is different than free speech. That means that someone can force you to not say something, but not force you to say something.
- The government cannot force you to update the canary. A court cannot get you to update it, because it's forced speech to demand an update.
- You created the canary of your own accord, and are responsible for its effects. Not updating the canary is, effectively, speech.
Though, from [0]:
"Realistically, though, courts compel speech all the time. Court-ordered apologies, disclosures, and notices are not unusual. And if ever a court would be inclined to compel speech, it would be in a situation like this one, where a company intentionally set out to get around a gag order with this kind of convoluted sea-lawyering."
Decoupling your physical mailing address from your office location makes a lot of sense, since changing the address would be very disruptive. Same reason you'd use Google Voice over giving someone your direct number.
And more and more companies these days don't even have any fixed physical offices, with remote-first cultures. What's the address of Trello? You won't find it on trello.com
It's not like you're going to actually walk there. If it's a legal address registered for the company, that's enough for every interaction you need with them.
It's unfortunate that you're being downvoted just for being cautious/skeptical.
Various aspects of rsync.net are periodically discussed on HN. About 417 days ago I raised a similar issue to yours, namely who is behind this company and what is the address.
At that time the owner responded on HN with clear information. It's unfortunate that, more than a year later, their website is still a bit of a dog's breakfast on this issue.
What makes my suspicious is that I can't find any information on the company itself anywhere on the site. Where are they headquartered? What's their contact information? It's not even clear under what jurisdiction they operate.
Again, we had all of this in place prior to an ill-advised website redesign.
As I said higher up in this thread, I'll make sure this gets republished and put in place properly today and I will add some verbiage that addresses your specific point about HQ and jurisdiction.
In the meantime, I will confirm we are a US firm with locations (ie., our own racks - not rented hardware) in San Diego, Fremont (San Francisco, basically), Denver, Zurich and Hong Kong.
Phys-sec means you don't just advertise your location, and keeping control over how people can contact you is another way to prevent social engineering attacks.
