Google Testing Old Search Design?

"There have been several complaints over the past week about Google showing searchers its old Google Search design. Some of those search results seem to lead to a broken interface, while others just look like they are from a decade or so ago. This seems to be impacting both mobile phones and tablets, from what I can tell. This was first reported on PiunikaWeb who attributed it to Google simplying its search results but that is not it."

"This seems to be impacting both mobile phones and tablets, from what I can tell. This was first reported on PiunikaWeb who attributed it to Google simplying its search results but that is not it. This seems like a bug or some weird test... Here are some, not all, of the screenshots from those threads: Mobile Phone: Tablet: What it should look like: Some look completely broken as well: These seem more like a bug to me than a test or experiment."

Google Search is intermittently showing an older interface and, in some cases, a broken search UI to users on mobile phones and tablets. Some search results render a decade-old visual design while others produce broken interfaces that impair usability. Multiple users captured screenshots comparing the older layout to the expected modern design and posted them for evidence. The inconsistent occurrence across results and devices suggests a software bug or an internal experiment rather than a deliberate, permanent redesign. The behavior has prompted complaints and calls for investigation and resolution.
