I'm an MIT student and received the letter as an email. This was the URL linked in the email for the 'online version'.

I had the URL updated to the Office of the President's page linked by a poster below as it is certainly clearer / more immediately credible. Thanks for raising the issue and thanks to that poster for the link.

Interesting, it must be a analytics service they use to track clicks, it certainly makes the links look sketchy

.lu is Luxembourg. Why would the president of MIT's statement be on a server in Luxembourg? And "mjt"? Yeah, I'm not clicking on that to see what's there. No way.

Here's a real link: https://president.mit.edu/speeches-writing/reflections-and-p...

Here is the first link in your linked page (“I encourage you to read his letter”):
