Same here.

Same here, we often see micro outages. Pages is not available via cloudflare, but when monitoring the IP/webservice locally there are no interruptions.

Our internet line is stable, we monitor latency and packet-loss via smokeping. 1gbit up & down, no shortage of bandwidth.

Anyone from cloudflare here to check this issue? I'm also facing the same issue but the page seems to be working fine

Seeing this pretty regularly as well. Occurring in multiple different AWS accounts almost simultaneously.
