I think you missed the bit about 10Gbps. Another speed test server that looks to be connected via 1Gbps. Mind you the upload speeds seemed stuck at around 350Mbps, and that's a load of rubbish as I have 40 cores of Xeon 6138 goodness and 768MB of RAM and the boot disk is RAID1 SSD and other servers give something close to 1Gbps, and I definitely have 4-5Gbps out the University as I have tried a speed test between a couple of Universities in the UK for benchmarking purposes as a remote user was complaining about the speed transfering files on/off the system. I figure Egypt has some sort of ingress filters on their internet
Getting close to 10Gbps is tricky even within the HPC system. The storage servers have bonded 40Gbps, and I just can't max those out at all even between themselves and they are all on the same switch. The whole system has a redundant 10Gbps uplink to the University's core. Not sure what the uplink to Janet is, but pretty decent.
I have 1Gbps on my desktop at work and for general web browsing it's no faster than the 80/20 FTTC link at home.
