On Tuesday, January 29th 2013, https://learn.uwaterloo.ca went down. Without our beloved Learn, panic struck the hearts of all Univeristy of Waterloo students. This Ruby script checks if Learn is still down every 5 minutes. If it finds Learn not down, it ensures near instantaneous rejoice by sending you an email.
EDIT: Learn has since returned! However, this tool may be useful if Learn ever goes down again.
git clone firstname.lastname@example.org:elijahandrews/check-if-learn-is-not-down.git
gem install bundler
Enter in your gmail username
Enter in your gmail password (it's not stored anywhere!)
When Learn comes back you will receive an email at the address you entered.
