The Italian Diplomacy site is down sice October 1st 2014 and the Administrators of the site haven't solved the problem (or they don't want solve it).
I wrote to the Adms of the international site and this was their answer:
"Hi Maucat,

Basically you need to get some hosting, set up webDiplomacy on it, then enable the Italian translation for it. Then it's just a matter of getting the Italian players to move over.

If getting hosting is something you can't do let me know and we might be able to figure something out, but it'll take a while. The best bet in such a case might be to try and get in touch with the original Italian webDip site owner.

Regards,
Kestas"

I asked to the italian Adms a lot of time to do something to restore the site but without positive answer. They seem only interested in live game of the Italian and European championship (game limited to the 1907 moves-very noisy games).
I hope that someone can do something to help them to reactived the site or to take from them the control of the site.

How many users did you have playing on that site?

I don't know, maybe something around 100 or 150 players

It's a bit strange that this site disappeared that fast.
I think the owner of the site paid kestas to add language support to the webdip-code.

I had a discussion with one of their Admins, 3 years ago or so, and yes he confirmed they they only care about FtF competitions. They kept the site just like a showcase on the internet for the AID (Italian Diplomacy Association) and this is why they have never cared much about fixing bugs, crashes, mislinked borders etc.
So I told them that when the shop-window sucks nobody gets into the shop, so making it a better site - or at least a normally working site - could have been very useful both for the AID and for the online players.
Unfortunately looks like they have (or they *had*, likely) only one person with the required skills to run the technical side of the site, and it was also a very busy person. This was the reason why fixing the link I was asking for "could take no less than 8-10 months, if it will be possible at all" (sic). Wow, really very busy.
I joined that site 6 months earlier, not because I planned to play Online-dip on such a poor site (I already loved vDip for such purpose), but because I wanted to learn things about that community and possibly join some of their FtF games on weekends. But after I got such a disappointing reply on that and on other things we talked about, I just completed my current games and left it for good. They just looked like a slapdash gang to me with a very rough organization.
Pity, I was very curious about AID. But I'm almost never bored on weekends, I can live without it.

tl;dr: I believe that the person taking care of that site is dead or missing and the site followed him.

No, they are alive and simply they aren't interested in managing the site. The italian players of Diplomacy are abandoned to themselves.
AID is a little association organizing very little tournaments of a boring variation of Diplomacy, it's leading to Death the Diplomacy in Italy.

Hello, i'm an italian member of the diplomacy association. i know Alex (the owner of the site) and i know what happened.

The problem is simple: their host made an upgrade to the software and their version of webdiplomacy stop runs 6-7 months ago. 1 years ago something similar happened for 6 more months of stop. The problem is what Guaroz told you, Alex, and other italian members, don't care about the online game and only think to make their own f2f tournament. Who cares about the site haven't the skills to fix these kinds of problems and can only try to convince the owner to handle it.

I know that there is an italian group, bored of waiting probably, that start a new site to play diplomacy and used vdiplomacy as base (that i think is better than standard one).

We can only wait and see what will happen.

I'm on italian site from the middle of 2011 and from that date until October 1st 2014 there was only short interruption of maximum 2/3 days, no long interruptions.
I think that without a working site their f2f tournaments will quickly fell to under 10 players but Alex & co. will be happy to win them and be proud to be italian champions of 1907 Diplomacy...!!!

you probably have forgotten the start of 2014 where the domain exipired and, after Alex refuses to renew it, the host delete the site. Only after 4-5 months sameone convinced Alex to pay again and make the site available.

even if i like to play the 1907 variant i agree with you with most of your arguments, but i have to invite you to join us and make some costructive proposal to improve the diplomacy's hobby in italy.

I speak no Italian whatsoever but I could host for a discount, just covering my own expenses.
Guess that isn't the problem though?
