Questions

I followed the advices I got here and refactored the code.
Yet, sometimes the website is down, Instance count jump to 8, and yet, the website is crashing

This the charts I have when Instance count jump to 8, and website is not available

This on Standard S1 plan

The graphs depict various metrics like HTTP server errors, data input/output, requests, and response time, showing fluctuating activity around 11 PM UTC-04:00. (Captioned by AI)

The image shows a dashboard of key metrics, including HTTP errors, data in, data out, requests, and response time, for the last hour. (Captioned by AI)

When it happen I need to change the plan to Premium v3 P0V3, then it stable. Problem is that the Premium v3 P0V3 cost $127 / month …

It’s happen recently more often , not only when I send newsletter.

Is it normal?

Is Umbraco only works properly with the more expensive plan? (Premium v3 P0V3)
Is Standard S1 not suitable to Umbraco 16?

Thanks.
