TBS cam is down. TEPCO cam is showing spiderwebs:
Futaba cam, which looks out at the daiichi site, shows sky glowing:
I don't know what the spidercam phenomenon represents. It is possible that 'radioactive' water on the lens is producing the effect, but its also possible that the spiderwebs and orbs are some sort of energy produced by the interaction of very radioactive metal and precipitation. Remember the 25 sievert an hour vent tower (here).
I don't know the cause, but there is a reason the TBS cam is off and the spiderwebs could possibly be it.
