I don't get it: the potential user has to use some kind of computer/smartphone/non-kosher device to make use of this server. Not to mention all the network infrastructure in-between!

Is there a rabbi here to enlighten us?

[bszupnick]

Not a rabbi, but I am Jewish.

A specific segment of Jews (namely Ultra-Orthodox) have quite a complicated relationship with the internet. On one hand, that community has experienced the positives of this technology, but they also VERY much discuss the fears and downsides.

So this site can be a seen as trying to wiggle into that tough space of getting use out of it, but in an "acceptable" way.

Here's another example I found by a quick google search: https://koshercell.org/

But in Israel there's also a well-known ISP that filters the internet for you (and your household): https://www.linkedin.com/company/internet-rimon/

Interestingly, all ISPs and phone companies in Israel are required to offer server-side filtered internet for all customers who request it, at no extra cost.

According to the bible you or possessions or servants aren't allowed to "work" on the Sabbath (On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the sojourner who is within your gates.)

Rabbinic Judaism expanded this to the Jews doing "work" for you. Since this server is hosted in Israel and there are Jews who work for electric company on Sabbath. In addition the he doesn't want the server to work so he has it "work" only on a day when there isn't Sabbath anywhere in world.

Why should at least the smartphone be non-kosher if it isn't charged and switched on/off physically during shabbat?

I agree about the rest of the infrastructure though.

But you have to agree on some standard what "work" and "fire" is, though. You can't cease all electron movement from Friday to Sunday.

This whole thing is not required for Judaism at all.

I see it as an inside joke or maybe an art project.
