Resolved - As this issue affects only this one search we have resolved this outage and will track the issue, which we believe is a bug, through GitHub. (11:06 UTC — Feb 1)
Investigating - After investigation we have determined searches through the Chocolatey.org packages page are working, with the exception of the search for eclipse. An issue has been raised on GitHub for this. We are continuing to work to determine the basis for this but as it affects one search term (and we have tried many!), we have lowered the priority.

Investigating - We are seeing reports of timeouts when searching the Chocolatey.org website for packages. We are currently investigating. (15:02 UTC — Jan 30)
