I has been a few weeks since I could properly update my portable apps with the Updater.
The downloads the connection speed slowly goes down and eventually the connection drops, an error message is displayed and to whole process fails.
Some screenshots of the problem.
Interestingly, manually downloading from the website works flawlessly, in an instant (I'm using an 100Mbps connection, in São Paulo). I've tried every day since the problem started, to see if it was only a CDN fluke, but the problem is persistent and consistent; also, happening in my other machines too.
