I'm currently in the process of moving all the services I host to a new server, and the GraalCenter stuff won't be making the move.
The following services will no longer be accepting new content within a week or two:
All of the content on GraalCenter Pastebin and GraalCenter Uploads will remain online indefinitely. The content will continue to be hosted from S3/CloudFront as static files, so you needn't worry about anything disappearing. I have hundreds of my own files and pastes hosted that I don't want to go away, so anything you've already uploaded is safe.
Sorry about the news. Obviously these sites aren't insanely popular, but a few dozen people are using them per day, so I thought I'd leave a warning here before disabling them.
