Hi, new user here.
I want to confirm that I have the same slow download speed issues as TELLES0808 is experiencing.
Downloading construct2 r84 took me 20 minutes at 20-30 K/sec yesterday.
Today I downloaded r86 and again it was painfully slow.
Just to check my own connection, I SSHed into my online webserver, got the file directly from scirra and then downloaded from my webserver to my PC at my full connection speed.
So as far as I can tell, the slow speed is related to scirra server and not my own connection.
Maybe you aren't allowing multiple http connections or something?
