So my downgrade kicked in today. 200/200 -> 100/100.
Since my line could only manage about 12-15MB/sec on NNTP with a ton of connections, I figured at 100mbps it would be full line speed. Fired up an NNTP download and was seeing anywhere between 7-11MB/sec, mostly around 9-10MB/sec. I was ready to start complaining at someone, when something made me change to the Usenet provider's US servers. Instant. Line. Speed. Switch back to EU - unreliable garbage.
Can only conclude your current EU carrier is a mess of epic proportions. Now I'm wondering if I hadn't downgraded and had tried US-based downloads, if I could've maxed out my line even at 200mbps.
@PBCool - are upgrades also restricted to being actioned on the 1st of each month like downgrades?
