Joseph Tinsley, an SEO specialist, used Twilio SMS to create an alert system for his niece when her college's registration page was down. The site had been down for hours and thousands of students were vying for the same class, making it a first come first serve situation. Joseph set up a cron job to ping the school's website every 5 minutes and text him when it was back up, allowing his niece to register for classes as soon as the site came back online. Without Twilio SMS, they may not have been able to take advantage of this small window of opportunity.
