Unless "platform engineers" includes "deveopers", they're not the only ones who can diagnose an issue. Once at my previous job (providing a name based on a phone number to the Oligarchic Cell Phone companies), our service just stopped. I wasn't there during the outage, only heard about it after the fact. The servers were fine (they were not out of memory, nor did they have an outrageous load). The network was fine. The program just wasn't serving up data. There had been no recent updates to the code [1] so it shouldn't have been the software. It took the main developer, who knew the code, to know that a "this should not happen" situation, did---that is, the name query we used for a health check had been removed, and thus our software took that to mean the name service was out of commission, thus shutting down. Now, it could be argued that was the wrong thing for our software to do, but it was what it was, and no amount of SREs or "platform engineers" would have solved the issue (in my opinion). [1] The Oligarchic Cell Phone companies do not move fast, and they had veto power over any updates to production.
