Mmm your BT connection does look pretty good indeed.
Still seeing congesion tonight on Zen but not as bad as was yesterday - but peak time seems to be around 9pm so I'll report back later on the evening. Either way it will need addressing.
Support said they have put a "ping monitor" on my connection - wonder where they are pinging from.
Will update in due course!
