I noticed that the custom lightning maps were not updating all day yesterday and continuing this morning.
At first the maps would not increment the top bar times. I got it working for a while, then the strikes.txt went to zero file length and all the strikes after a point disappeared.
Thanks to Ken True of Saratoga-Weather who pointed out a server change. I updated the appropriate scripts and is seems to be OK now.
Sorry for any inconvenience, this was due to a change at Blitzortung.org. The files that build the maps are now served from Lightningmaps.org.
