Hi
About a month ago i was getting rather bad speeds on my 20mbit service, even posting some speedtest.net links into this forum. But then everything resolved itself and i was back to getting between 10-20Mbit on my downloads. Well yesterday it seemed to drop back down to the same rubbish speeds again (less than 1mbit) and browsing some sites becoming very painful.
I decided to do some tests over night to get some data together and was surprised to see that between 1am-4am my download speeds magically jump back to normal, only to collapse again come 5am. You can see the data below in my graphs. As i can hit 20Mbit at certain times of the day, i assume this isnt an issue with the equipment myside and is perhaps is a congested UBR at virgin's side?
At approx 9pm, i started downloading large files from 3 colocated servers, 2 in the UK, 1 in Amsterdam and had 3 connections downloading from virgins Newsgroups. You can see the paltry 1mbit service i was getting until around 1am when it suddenly jumped to around 10mbit and 4am when it jumped to around 20mbit, only for it to drop to around at around 5am. I woke up and stopped it around 6am. I was not capped before i started the test as the line had been so bad all day, it would have been impossible.
Speedtest from about an hour ago
Downloading from gamefiles.virginmedia gives an approx speed of between 70kb-80kb
