Photo not uploading

Generally I think I suffer from Peak Period Sickness. I begin the day with 6Mbps down and 0.3Mps Up
Evenings and Sundays and a few other ‘peaks’ I am 1.3 or less Down and .22Mbps Up.
I know my Exchange 5ks of copper away is low grade, so I suspect peaks are caused by local internet users.
Even if I pay for FibreO I will still have nearly 2kms copper.
Until a month ago I was uploading 7Mb pictures - perhaps a bad habit - see Photo size restriction?
I DO believe, but obviously cannot prove, the iSpot Server sometimes responds extra slowly. Might it recognise me and my style?
What is your UPload speed on average?
