Currently, I plan to use the free plan CDN.
The site I operat is regularly being layer 7 DDOS/DOS attacked.
The attack time is 1-5 hours, so by viewing the cloudflare server cache
I would like to know how much I can avoid downing the site.
*Under Attack Mode will not be used if possible.
The questions are as follows.
I think the free plan CDN has a cache retention period of 2 hours.
In an attack within 2 hours, even if the origin host is down,
Can cloudflare’s server cache be viewed and the site down be avoided?
2 Is there a way to extend the cache retention period by using the free plan CDN?
For example, during a DOS attack, by operating the dashboard and updating the site,
Is it technically possible to extend the cache retention period with each update?
