Help? Cloudflare and ISP Host Conflicting over IP Address

[Blatchley, Carolyn]

We have a Drupal site hosted with a service provider. We also have Cloudflare for filtering out DDoS attacks.

Recently, traffic to our webserver appeared to be blocked by Cloudflare. Through investigation, we narrowed it down to one IP address that Cloudflare uses which is not getting through to our hosting provider.

Our provider (who recommended using Cloudflare) insists that the IP address in question has been whitelisted. However, every time we re-enable Cloudflare, our site is unreachable and the tech people at Cloundflare say that they can see their IP address being blocked by our host. This results in our site appearing to be down.

Does anyone have thoughts on how we can resolve this? The two companies both blame eachother, and our library customers are frustrated by the site going down frequently.

Thanks in advance for any help you can provide.
