I will admit that I paused after typing that, but then I figured, as another commenter mentioned, that with PagerDuty being popular, it wasn't too much of a stretch.
Admittedly, I'm someone who has carried an honest-to-god pager, the "start the number with 911 if it's an emergency" sort of 10 digit segmented LCD ones. Even remember enjoying the freedom of getting upgraded to one of the national ones when traveling!
Though I'm currently thinking about switching from PagerDuty to ntfy.sh/pushover, as it's really hard to justify almost $50/mo per person with Pager Duty for the use my small team makes of it.
I'm not sure how many companies still use "pagers" aka "beepers", but this person is talking about the device you carry that would alert you when there is a problem with one of your systems. https://www.google.com/search?sca_esv=593535494&q=pager&tbm=...
Before mobile phones and beepers, institutions would use a public address system to announce “paging dr. whoever.” Makes me wonder whether the word comes from sending a “page” (an errand boy) to go look for dr. whoever and bring him back.
I guess now “carrying the pager” is a metaphor like “copy and paste” (from the glue used in newspaper layout).
