Something went wrong at our end

What this means

Something failed at our end. Nothing about this one is your doing, and nothing you change about the request will fix it.

Why it usually happens

A defect in our code, or in something we depend on.

What to do

Try again in a minute, and write to hello@packagepage.com with what you were doing if it persists. One thing this never touches: printed codes keep resolving through it, because the resolver answers scans from a local copy with no database on the request path.
