We had a minor issue today with the database today. A couple tables (user/attachment views) were crashed (the attachment views were crashed for about a week, and users for about a hour), so that was fixed with some minor downtime. For the past 7 month, the speed of web pages as well as attachments haven't been as fast as they should be. Apparently, our server's speed isn't 1 Gbit even though I've been paying for it. The server techs are currently working on fixing that; I will update this post as it is resolved. In addition, we had some issues with our cache server giving users random IP bans. I'm pretty certain I have resolved this issue. (02/17/12) Edit: Caching disabled completely. It appears that the database corruption wasn't completely fixed. I took down the site for a hour and did a full database repair, no more lag..
Since the skin release in January, I've been adding and upgrading the skin/plugins. A couple plugins, such as experience and the shop, are missing and have to be upgraded/optimized. I'll be rolling out those upgrades as soon as I get some free time.
As for hacks, spring is coming up and this year, like last, I'll be working on a few public pubs. Keep an eye out because we're going to be having releases all spring/summer long!
