I manage a team of tech support engineers at pantheon.io, where we host Drupal and WordPress websites. We use PD on the Support team for handling emergency tickets coming in from our biggest customers.
The first time I ever got paged was due to performance degradation on a high-traffic food magazine site that was under a DDoS attack. Someone really hates fancy sandwiches I guess.
Before getting into support, I was a web dev for about 10 years, doing mostly PHP/JS work.
I’m the on-call backup this week, fingers crossed for happy internets.
