Hi,
Like many others, the CC updates are (were) extremely slow on my system although I have a decent ADSL connection. I gave this some thought and found the following...
Adobe are distributing their software through the Akamai CDN (this can be observed with a network monitor while upadting). For those who are not aware of this technology and to make things simple, a CDN is a system that is able to make the downloaded package available to a myriasd of servers all over the world and to connect you to a server near your location (which is detected from your IP).
This works automatically but not always, especially when you are using a DNS server that is not able to provide localization information to the CDN system. In which case, you are systematically downloading from the central server. If you are living far from Illinois, this can slow down operations a lot. A good example is when using the Google DNS servers (8.8.8.8 and 8.8.4.4). This can also happen for some internet providers. I made some tests and I could observe that indeed, I was always downloading from the central server in the US (I'm based near Paris in France).
Given this information, I thought to myself that if I could use the Akamai DNS servers instead, I may have more chances to download from a nearer server. Fortunately I could find the IP addresses of the Akamai servers :
- IPV4
88.221.162.120 and 88.221.163.120
- IPV6
2620:119:35::35 and 2620:119:53::53
I changed the network settings on my system to make it use these DNS servers and I could immediately observe that I was now downloading from a server in Frankfurt (Germany). And the update was significantly faster. I wouldn't say lightning fast (I only have a 10 Mbps ADSL connection) but this was more acceptable.
I cannot guarantee that this will work for everyone but there's no risk trying. I didn't observe any side effect since I have changed the DNS servers.
Hope this helps.
