seeing errors in logs
Using Jamroom
During the maintanence schedule some servers needed a reboot after system updates. For some reason they got hung up and couldnt communicate with jamroom.net during the time they were hung up. The servers were all still working, but things like the marketplace system couldn't get updates.
If you see errors related to communication with jamroom.net thats this.
your second screenshot seams to be related to amazon S3 not being able to back up the Vimeo module. doesnt seam realated. would expect that you can download the vimeo module from jamroom.net if the backup of it didnt work for any reason. See if it happens again next time the S3 backup runs.
