I had to renew the Gyaankosh domain name recently and tried to check in to the site. What I found was that the site was down, and has been down since June. It seems my webhost transferred my account to a new set of servers, and this transition somehow interrupted service (despite all assurances to the contrary).
So, over the next few weeks I will be moving Gyaankosh to a more reliable webhost. It will be a replica of the site before it went down in June. Once it's back up, I will move forward with a number of planned improvements (including catching up on recent packets).
Unfortunately, I do not have much free time right now, so I can't promise a date when everything will be fixed. When it does go live, I will announce it in this thread. Otherwise, I rarely peruse the boards, so PM me if you need to get in touch.
