I just tuned in at 10:29. The cloud/TWC logo was where the LDL should have been, and when the "Wake Up With Al" segment started again, the national LDL is being shown instead of the IS2. (My cable company repeats the HD feed on the SD channel, so I can't comment on what the SD feed's doing here.)
I'll have to wait a few minutes to see what happens with the local forecast.
Edit at 10:42: The IS2 local forecast came on just fine, and now the IS2 LDL is working again, too.
Edit at 10:50: The national feed HD local forecast came on, and the IS2 LDL was on for about half of it.
