Usually I go on the GCN (NGC) section and I'm downloading one right now as I post this at about 700 kb/s (pretty good for my internet speed of 300mb/s while doing lots other surfing and my internet is randomly slowing down and I have to do double loading), but on the odd day it suddenly drops to something like 100 kb/s.
Which day/s is/are there usually a lot of traffic for this section?
