Hi,
I have a Gigabit cable internet subscriptions with UPC/Sunise/yallo.
I noticed today painfully slow downloads from various servers, around 40 Mbps instead of 1 Gbps.
To investigate, I performed speedtests to several servers using Ookla’s CLI (see below).
- One of them (first result) consistently gives 800 Mbps,
- but all the others I tested yield only ~40 Mbps in download.
On the other hand upload speed seems constant at roughly 100 Mbps, as expected. The servers and myself are located in Zurich.
The machine doing the tests is connected directly to the Connect Box via Ethernet, and nothing else is happening on my network. I tried restarting the Box and everything else, without changes. The results are consistent across multiple machines.
The fact I reach 800 Mbps on at least one server points to an issue on Sunrise/UPC’s side, not to my local setup. Peering problems?
