This article is talking about Iranians being able to use AWS to host services. We are talking about services I host on AWS being accessible in Iran without a VPN.
Those are also blocked, but I genuinely implore you to make an Iranian friend (somehow) and ask them what works. For myself, I saw my users go to zero when I migrated to AWS+GCP over my European based co-location provider. I was hosting services that had 30,000~ monthly active users from Iran at the time. https://en.wikipedia.org/wiki/Internet_censorship_in_Iran#Un...
Maybe your issue was due to use of GCP?
I moved all my stuff to AWS specifically because Google Cloud does have this kind of block. I care about this a lot, so if your friends in Iran have different things to report, let's look into it to figure out what is going on.
