Actually, Stall Catchers itself is fine, but Amazon Web Services is down. Because Stall Catchers depends on these services to load the vessel images, there are currently no images available.
According to Amazon’s status page:
We’ve identified the issue as high error rates with S3 in US-EAST-1, which is also impacting applications and services dependent on S3. We are actively working on remediating the issue.
We expect this service interruption to be brief (it is Amazon after all), but we honestly don’t know how long it will last. I called Amazon and asked them to try turning all their systems off and back on again, but they didn’t take my suggestion seriously for some reason 
Anyway, thanks for your patience and we hope this will be resolved very soon! In the meantime, if you haven’t visited the EyesOnALZ blog or Facebook page in a while, check it out!
