Magically it seems to be functioning again, although the graphs show a blank for the 18th Sept. If I click on the text report for the month each day is complete.
To be honest I find the graphs and pie charts a bit... quirky. However, it's the numbers that are important.
The 4 hour thing is good to know. I assumed it updated more frequently, but at least I know what to expect. So that's ok.
One final observation, bandwidth warnings are sent out at 80% capacity (for some reason I always get 2), but nothing after that. Reminders at 90% or 95% would be useful. Do they occur? I've come close to 100% and did not receive one.
Thanks.
