maximus reminds me of my area some years back.
Constant upstream congestion for years on end, then was the 10:1 network upgrade program, and the upgrade work was carried out months before they upped the speeds. I remember for about 3-4 months experiencing the level of service some get on here all year round and was great, sadly they moved some users onto my node from the blackbird road node as those guys were getting congestion (instead of actually upgrading that node they did the cheapest option), then I was starting to see signs of congestion even before the speeds got ramped up, then the day they activated the higher speeds there was clear congestion the moment they flicked the switch. Either they were/are very incompetent or its the beancounters saying no go on upgrades unless is for marketing reasons.
Really this need to hit 90% utilisation is such a silly threshold, and its still in place now.
