The social networkig world slowly ground to a halt today when both Facebook and Twitter stopped working. Both sites slowed to a crawl during the day presenting users with a miriad of technical errors and connection issues.

Twitter confirmed this afternoon that their site was hit by a Denial-of-Service attack resulting in a complete collapse of their servers. Essentially a DOS attack overloads a server with false hits, overwhelming it and causing it to shit down. Facebook have yet to comment on their service issues but one should imagine that they were facing similar attacks most likely from the same individual.

This must have been one rather anti-social hacker, not that one would suppose the hacking community comprises the most outgoing and convivial bunch of peeps.

A service I knew very little about until today, Google Voice has officially started sending out invites to its service. I would explain precisely what the service is but this video does it so much better. Looks amazing, I can’t wait to use it.

In the past, we’ve speculated that Apple’s resistance to supporting Adobe’s Flash on the iPhone and their efforts to add new features to HTML/CSS is, in part, to reduce their long term dependence on Flash.

Ajaxian points to an impressive demo by Charles Ying which shows off hardware accelerated 3D CSS Visual Effects that are now supported in Snow Leopard’s Safari builds as well as the latest Webkit nightly builds. If you have either of these versions installed, you can view a live version yourself here. Otherwise, you can watch this video of the demo:
