LOL. Microsoft accidentally “DDoS” npmjs.org in the new VS Code release. This is due to a feature in VS Code 1.7 sending a lot of non-cacheable requests. Thankfully they responded quickly and reverted VS Code to the old version.
These typings files drive the IntelliSense (code completions) experience in VS Code. The feature was so great that we started to overload the npmjs.org service.
