I’m not sure if Twitter has officially retired the “Fail Whale” landing page that we all grew accustomed to over the years.
But I recently came across a Twitter error page that did not include the whale, though did include a number of languages.
The page defaults to the user’s browser language, so I initially saw an error page in English.
Clicking on the language links in the footer quickly changes the language of the error page.
Shown here is German.
I’m assuming that English is the fallback language for instances in which the user’s browser is set to an unsupported languages (such as Swedish).
Over the past two years I’ve seen an increasing number of companies localize their error pages.
These details really matter.
