Coding for Google SoC this summer

I just received the following in my mail:

This means that my project proposal was accepted, and that I will get to spend much of the summer working on a browser user interface for gRavi, mentored by Ravi Madduri of the Globus Alliance and Argonne National Labs.

You can find more details about the project in this google doc.

Is YouTube down?

For the past 2 hours, I've been unable to get on to YouTube.

It's on the scale of unlikely that  a service with the administration and infrastructure of google would go down, but it's only a year and a half since it happened last time (which was the first time).

So is this the second of biannualish youtube failures? 

Update (2:55) - The site is back up and running. Here are some interesting theories on what happened:

• Server maintenance to add AddSense
• DNS accidentaly remapped
• DNS hijacked
