This has been posted on some of the other boards, but I'll mention it here just in case.
The webcam didn't actually crash today. Directly in front of the Magic was a US Navy submarine that showed up unexpectedly at the Canal this morning. For security reasons, whenever a military vessel approaches one of the webcams, they shut the webcam down. The Miraflores webcam actually stayed up a bit longer than the others because you could see the submarine on that cam for awhile. As soon as the sub had passed, they would turn the webcams back on.
On another thread they mentioned that there was supposed to be a helicopter taking pictures of the Magic as it made its transit today, but the helicopter was grounded because of the sub also.
