"Very poor. Real-time Internet application performance will suffer greatly on such a connection. Test to other servers to confirm the result, but definitely talk to your ISP about troubleshooting the issue."
The grade was an unflattering F. Ping 91 msec, 35% packet loss, jitter 15 msec. This test was done mid-morning from Dunedin. A speed test from www.speedtest.net shows a respectable 3.5 Mbps download, but this can drop to as low as 200 kbps in the evening. Yes, I did e-mail Xnet about slow evening speeds, but didn't receive a reply.
Anyone else care to carry out the same test and report back?
