Hi,

I work for CloudFlare, a reverse proxy/CDN/DNS provider based in San Francisco, CA. I've run into an interesting issue with some users on a Blackberry device, and it looks like Blackberry *might* be blocking some of CloudFlare's IPs. Here's what happens:

1. Customers accessing a CloudFlare enabled site via wi-fi don't have any issues.
2. If the user accesses via the BB network, then it goes straight to a 10005 error for some of their visitors. After looking at some of the causes of 10005 errors in your forums, the only thing I can think of is that our IPs are being blocked or limited in some way. CloudFlare's IPs are:

• 204.93.240.0/24 (204.93.240.0 - 204.93.240.255)
• 204.93.177.0/24 (204.93.177.0 - 204.93.177.255)
• 199.27.128.0/21 (199.27.128.0 - 199.27.135.255)
• 173.245.48.0/20 (173.245.48.0 - 173.245.63.255)
• 103.22.200.0/22 (103.22.200.0 - 103.22.203.255)
• 141.101.64.0/18 (141.101.64.0 - 141.101.127.255)
• 2400:cb00::/32 ((2400:CB00:0000:0000 - 2400:CB00:FFFF:FFFF)

Note: The only range I can confirm this has happened with would be this one: 173.245.48.0/20 (173.245.48.0 - 173.245.63.255)

Is there a way to check to see if Blackberry is blocking requests?
