Performance issues faced from 19th June to 20th June 11 am IST

From yesterday, we are seeing loading issues in the StoryWeaver site all of a sudden and we found the root cause of static assets like png and svg assets loading was taking minutes together which are supposed to be cached at Cloudflare.

All of a sudden, now at June 20th around 11 am IST - things became normal again. Our site was almost non functional from June 19th morning till June 20th 11 am IST

Was there any maintenance activity that got carried from Cloudflare side?
