AT&T is blocking Tutanota in some US regions. As AT&T has not fixed the issue after more than two weeks, we are reaching out publicly in the hope of getting the attention of the right people at AT&T. Read more on our blog: https://tutanota.com/blog/posts/att-blocks-tutanota #netneutrality

@Tutanota You're right.Net neutrality is really important to keep the freedom of the Internet.Without net neutrality,decentralized platforms like Mastodon or Matrix could get serious problems 😢 But do you really think that AT&T is censoring your service?That would totally be possible but I don't see any confirmation.Maybe it's just a technical issue they're too lazy to fix.What I'm really shocked about is that they have the possibility to censor websites 😲 I thought the thing with net neutrality is all about unfair speed advantages but not about blocking.
@nipos Actually, we don't know. It's not a routing issue, we've tested that. We're now in contact with AT&T so most likely it was a technical issue. But before going public with this, we weren't able to get their attention...

in England I've seen big corporate services like Dropbox and Sage Drive (used for accounts systems) made inacesssible or intermittent due to a misconfiguration at an ISP, and even that took about 2 weeks to resolve (and the ISP logged the ticked immediately) - I had to get some of the Accounts department staff to work in a different office next door - ironically this was connected to the *same* ISP but via a different network backbone!)
