various parts of janet, usually 100mbit or 10mbit ftp servers.

I think there are a very few JANET sites that use ntl as a backhaul to the rest of JANET on perhaps 2Mbit up to at most 155Mbit circuits however apart from those isolated examples ntl supply JANET with fibre wavelengths only over which JANET run their 10Gbit goodness.

JANET and ntl peer, ntl do not supply JANET with external bandwidth, it's just a normal private peering.

so either my transit didnt go over that private peering or something is saturated en route?

For instance, in our case, most of our student facing servers (ftp, user areas, email and web servers) are fairly up to date. However, some of the servers for our internal stuff are way out of date. For instance, the database server used to enable web access to student details is a P90!

Also, Unis don't necessarily have fast enough links (again, due to budget). Where I work, we are lucky. The Campus was only opened in 1999, so our networking hardware is (relatively) new. The main Computing department (who manage the network for the whole University) is also based here, so the link tends to get upgraded frequently, and is well maintained.

the uni's i downloaded from had total capacity that could give 10mbit speeds with ease but for some reason to ntl speeds were very low around 40kB/sec, they could send at 3000+kB to germany fine tho. Saying that they were slow to few other uk isps also, but I just asked because if it was going over direct peering it shouldnt be anywhere near as slow as 40kB.
