I’m not aware of one, and I don’t see any indication of a major problem when I check Downdetector.
I have five of the original Plugs, and those that were already plugged into power show online in the app and work as expected. One Plug was in a drawer, so I plugged it into power. It didn’t appear to do anything, so I pressed the power button on the side several times and unplugged it and plugged it back in. It flashed blue for a while, so I decided to let it sit, and it seemed to establish a Wi-Fi connection within a few minutes. 
If you’re still having the issue, then I’d consider power cycling the Plugs by unplugging them and plugging them back in.
