+summary: Consolidating our web sites onto go.dev.
+---
+
+In 2019, which seems like a decade ago, we [launched go.dev](/go.dev),
+a new hub for Go developers, along with the [companion site pkg.go.dev](https://pkg.go.dev/),
+providing information about Go packages and modules.
+
+The go.dev web site contains useful information for people evaluating Go,
+but golang.org continued to serve distribution downloads, documentation,
+and a package reference for the standard library.
+Other sites — blog.golang.org, play.golang.org, talks.golang.org,
+and tour.golang.org — hold additional material.
+It's all a bit fragmented and confusing.
+
+Over the next month or two we will be merging
+the golang.org sites into
+a single coherent web presence, here on go.dev.
+You may have already noticed that links to the package reference docs
+for the standard library on golang.org/pkg now redirect to
+their [equivalents on pkg.go.dev](https://pkg.go.dev/std),
+which is a better experience today and will continue to improve.
+As the next step, the Go blog has moved to go.dev/blog,
+starting with the post you are reading right now.
+(Of course, all the old blog posts are here too.)
+
+As we move the content to its new home on go.dev,
+rest assured that all existing URLs will redirect to their new homes:
+no links will be broken.
+
+We are excited to have a single coherent web site
+where everyone can find what they need to know about Go.
+It's a small detail, but one long overdue.
+
+If you have any ideas or suggestions, or you run into problems,
+please let us know via the “Report an Issue” link at the bottom of every page.
+Thanks!
