It doesn't matter. It's not an attack on a specific web server, CMS, or even database engine. The ONLY thing that matters is if the underlying scripts driving the website are poorly written and vulnerable themselves.

It's not difficult to write something that spiders websites and attempts injection attacks against querystring variables that that individual site commonly uses. The exact same thing happened either late last year or early this year. Now in that instance, that was specifically targeted for MS Sql Server, but it's not hard to imagine a completely platform-independent version.

One of the major features of the patch was adding a new LFG system that literally makes finding a group trivial. If you're just looking for a random instance, you'll be in a group within minutes. If you're looking for something more specific how long it will take will obviously depend on what instance you're looking for.

The key thing is that it's all automated now - it'll find 4 other people (with correct roles - 1 tank, 1 healer, 3 DPS) and automatically group them together for what they're looking for.

By "try again" they mean "try teleporting to the instance again".

There's an icon in the lower left corner of the minimap that you can click to try teleporting to the dungeon again. No need to drop group and look again.

"'There's a rounding-error bug in the camera driver's autofocus routine (which uses a timestamp) that causes autofocus to behave poorly on a 24.5-day cycle,' said Morrill."

Cool! The device will later be fixed to properly behave poorly only every 24.45 days!
