It really depends on what the application stack is. Is it using a service mesh? A DB? Queues? What about the web server logs and metrics? 503 (I'm assuming) errors are generally point to your application. They could turn up for a variety of reasons, load being a very common one. Could be more complex involving other parts of the system or a bug. I would try to get as many logs and metrics as you can. May help to establish some sort of pattern to narrow down the problem.
