What I Wanted to Do
Sign up for an account on npmjs.com and verify my email address from my phone
What Happened Instead
I just created an account and was sent an email asking me to verify my email address. It contains the link https://www.npmjs.com/verify/4aa3f730-ea35-4684-94ef-b6359c18716f . I tried following the link on my phone but repeatedly got 404 errors (with the cute wombat). I then tried opening it on my laptop and to my surprise it worked.
Trying to open the link again (after the successful validation) on my laptop yields the same 404 error I got on my phone.
