As PagerDuty and our customers grow, we've had to make some adjustments to keep things running smoothly. Historically, we made sure that incidents in your account started numbering at incident #1, from day 1, and never skipped a number…ever.
Unfortunately, guaranteeing chronological incident numbers means that sometimes, we can't create new incidents quickly enough. To address this, we've made a small change:
Going forward, you might notice some "missing" incident numbers in your incidents list. We don't delete your incident numbers, so if you do see a skipped number, you'll know that the number was skipped at the time of incident creation.
This shouldn't happen often, and it doesn't indicate a problem; in fact, it means our system is doing its job! Please contact our support team if you have any questions about incident numbering.
