I've recently been having problems updating my Adobe applications over my 350Mbit broadband. The connection starts fast but then rapidly diminishes to only a few k/sec and eventually the connection breaks and download fails. I've been able to replicate this problem on both my PC and my Mac. To rule out my computers, I used a VPN to connect to a different country and was able to download the updates super quick. I also created a 4G hotspot with my phone and used that on my Mac and again, I was able to download really fast. To replicate the issue I tried to download just the free to everyone Acrobat Reader on my PC without a VPN and it was slow then failed. Enabled VPN, same link and downloaded within a few seconds.
Having used two different computers, VPN and a 4G hotspot to rule out my local network, router or hardware as the cause, this points to a problem with Virgin themselves. I would be interested to know if anyone else is experiencing these types of problems (I'm in Nottingham), or what I should do next to try to resolve this issue.
