Resolved - Cloud9 reports that a fix has been pushed and has propagated to all hosts. If, after reloading the IDE, you're still seeing

/mnt/shared/sbin/node
ssh process died with exit code 255

please email support@c9.io and CC heads@cs50.harvard.edu so that Cloud9 can take a look!

Monitoring - Afraid Cloud9 is currently having an issue whereby the IDE is failing to connect to hosted workspaces. They're currently investigating, so we're hoping it will be resolved shortly. In the meantime, if taking CS50's on-campus quiz, consider focusing on question 4 (To be or not to be) and question 5 (Vantage Points), which don't require writing code.

Monitoring - Some issues have been identified by Cloud9 and some fixes were implemented. Please let sysadmins@cs50.harvard.edu know if you are still losing files or having them corrupted. Please include your CS50 IDE username and workspace name (which should be part of the workspace URL), a list of the affected files, and in case of missing files:
* any (estimated) timestamps of when the files were last modified and or missed.

in case of corrupted files:
* any (estimated) timestamps before or after the files were corrupted.
* any events you believe might have lead to the corruption.

Thank you!

Investigating - We have been getting reports about corrupted or lost files in some workspaces. We have reported the problem to Cloud9 and they have been investigating. We will follow up as soon as possible.

In the mean time, if some files are corrupted or lost in your workspace, let sysadmins@cs50.harvard.edu know your CS50 IDE username and workspace name which should be part of the workspace URL, along with the paths for the files in question.
