There are definitely issues.
At MK today and have been turned away for down rides at carrousel, 7DMT and BTMR.
We were there from April 12-18.
Epcot: LwtL was down when we first tried to ride around 9:30.
Later we finally got to ride it and ended up evacuated off of it (after floating backwards for 20 minutes or so, and waiting another 20+ minutes to be evacuated).
Mexico ride broke down for about 10 minutes while we were on it (which was only super annoying because we were with a group of LOUD high school kids + Donald Duck voice repeatedly).
Test Track: Broke down while we were on it, waited maybe 15 minutes? We got to re-ride as soon as we got off.
MK:
We rode 7DMT at rope drop and then went on Pooh, came off Pooh and 7DMT was down (so by 8:30ish?)
BTMRR was down when we tried to go on it.
Buzz and HM both stopped for 5-10 minutes while we were riding.
AK: Navi stopped for about 10 minutes while we were on it, that was it!
HS:
ToT was down for most of the day (noticed it down around 9:30, maybe? Was back up sometime between 4-6 when I checked but not before that)
RnRC was down for several hours in the morning
(Add that to a very long wait for TSMM and too early for shows and it's a sad park)
Other full day MK:
Splash and PoC were both down first thing in the morning, PoC for quite awhile but I didn't notice how long Splash was down for.
We also noticed 7DMT down later in the day, I don't remember when.
Luckily we managed a few hours at Epcot on checkout day with no issues!
So yeah, something is definitely going on. I kind of took reports of rides being down on here with a grain of salt, but once we were there it was clear it was an issue. It became a joke with my kids! Honestly, the whole trip was a very last minute gift from my mom and I paid for none of it, so it was hard to be upset, but it was still annoying.
