In a few minutes, we are starting a beta test to test a change in how some files that the software downloads, are delivered to you. This will help us continue to handle future growth as well as the occasional spike in download requests that periodically occurs.
We are going to use SoftLayer's Content Delivery Network (
http://en.wikipedia.org/wiki/Content_delivery_network) to support the download of certain files that are frequently downloaded. Most users will not notice a change as a result of this change. However, for users whose firewalls are set to allow the World Community Grid – BOINC software to download files from only specific IP addresses, you need to update your firewall configuration as per the instructions below.
Technical details for those needing to make change their firewall configurationCurrently, the files in question are downloaded from the URL:
https://download.worldcommunitygrid.org, which is associated with the IP addresses 170.224.194.69 and 170.224.160.205.
After this change, these files will be download from
https://BDD7.https.cdn.softlayer.net instead. With a Content Delivery Network, this URL is associated with a list of IP addresses, which is included at the bottom.
Check to see what IP address range you are likely to use at your location by typing the following command into a command prompt window:
nslookup BDD7.https.cdn.softlayer.net
This will return something like:
> nslookup BDD7.https.cdn.softlayer.net
Server: 9.0.128.50
Address: 9.0.128.50#53
Non-authoritative answer:
BDD7.https.cdn.softlayer.net canonical name = cs89.wpc.edgecastcdn.net.
Name: cs89.wpc.edgecastcdn.net
Address: 72.21.81.109
The line that says "Address: 72.21.81.109" will be within the IP address block that your location will use. You can find the blocks in the table below and you should enable that range in your firewall. The topology of the network periodically changes and you may find that you need to enable another network block in the future.
