I don’t see it on the website yet. What does it mean “released on servers”?
On the servers = The Amazon and Akamai-powered cloud infrastructure that hosts the content distribution network behind JW.org website. The publications are first uploaded there, replicated around the server farm for fast access from anywhere in the world. Only after that is the actual website updated (via their in-house content management system) and the publications visible in the usual manner. The URLs to the uploaded publications can be query by the so-called GetPubMediaLinks API call.
Has any change been made to an earlier version of the magazine that would explain the delay in publication?
The magazine was rewritten from scratch since Governing Body Update #2, even though the earlier version was ready for printing. The actual English language edition of the August Watchtower went to print today.
Have they removed the word disfellowshipping but not the practice? Or are they trying to water the whole thing down?
Yes, it's all word games. "Removed from the congregation" instead of "disfellowshipping", "committees of elders" instead of "judicial committees". One relevant change though is the discontinuation of warning talks if someone is marked for "walking disorderly", because now each individual Christian can decide for themselves whether to mark such a person, not just the elders.
