I switched from a Sky ADSL to a PlusNet fibre package on Monday 1st November. Things have generally been OK but I immediately noticed that download speed from a specific host very important to me is extremely disappointing.
I'm a developer and maintain several servers which run various services.
This one in Milan presents between 40 and 70KB/s download via HTTP (test file: http://data.1bpm.net/1GB.zip) which is in the region of 20 times slower than the non-fibre package I had with Sky (which was consistently about 700KB/s). Same rate with SSH/SCP. Upload is as expected and presents around an average of 2.1MB/s.
Download rates over UDP from that host are as expected.
I have another server in the same datacentre - traceroutes are fundamentally the same to both, but download from this second server is around 1.8MB/s which is fine/as expected.
Given that rates via Sky were as expected, traceroutes are the same and UDP is OK, I would suggest that PlusNet may be rate limiting TCP downstream from 37.247.55.137
I would be interested if anyone has any ideas and if anyone is willing to test the download speed of the file above on their PlusNet connection (it is just a random 1GB test file obtained from https://www.thinkbroadband.com/download)
