Aha! The thing I missed diagnosing terrible performance to my OVH machine (from my home network but not from other places) is that the first IP address on the path that is not my home ISP’s network (BT OpenReach) is 54.36.50.112, which is assigned to OVH Cloud.

In spite of being presented with the traceroute in the initial ticket, they failed to note that most of the traffic is within their own network and that they should be able to reproduce the problem.

The problem appears to be incorrect handling of fragment reassembly, combined with broken MTU path discovery (presumably something that is pretending at the IP layer that it isn’t fragmenting, but is for the lower-level protocol and is dropping packets?).

Alexandre Roure of the Computer & Communications Industry Association, whose members include many Big Tech groups, says the debate about blunt market access restrictions for non-EU tech companies “only distracts policymakers from the real task: finally delivering a functioning digital single market with clear, simple and practical rules”.

In private conversations, several Big Tech lobbyists and executives also express confidence in their ability to continue dominating the European market given the paucity of homegrown alternatives and the lack of urgency among many consumers.

Wow, #OVHCloud's customer support is really bad. They don't read the diagnostics that you've already done, they ask you to run tests that would give them no information (you've run iperf3 and it's fast with any remote client. Two other protocols are slow, but only over one ingress path. Please reboot into rescue mode and run iperf3. We don't know what information that will give us, but it's the next thing on the script and we have no actual brains and must follow the script). Oh, and they disappear for a week in the middle rather than responding to questions like 'what do you actually hope to learn from this test, do you have a hypothesis that would be either supported or contradicted by it?'

I definitely will not use them for anything important. I have a server with them that I was planning on moving things over to but I'm not even sure I want to trust them for personal stuff anymore, given that they are obviously completely clueless.

I guess the fact that their Kimsufi servers are so cheap (4x2TB disks in a machine for about £20/month) should have been a clue that they cut corners everywhere. I assumed it was just that the machines had already fully depreciated.

Are there any less-incompetent providers that offer cheapish (old is fine) machines with decent sized disks?

EDIT: I want to be able to move a few things to it, but also export a nice big iSCSI drive to my NAS for off-site backups. That means I want at least a few TBs of disk. I'd quite like to run bhyve VMs, so that probably means dedicated not virtualised (unless).

Really unimpressed by #OVHCloud's support. Finally gave up trying to figure out what is causing the network slowness. I'm 90% sure it's traffic shaping on one of their peer networks intentionally slowing / dropping ssh and wireguard packets. Every other protocol that I've tried is fast and ssh is fast from other machines.

So far, they've asked me to do a whole pile of irrelevant nonsense with no clear idea behind it other than, perhaps, to make me give up and go away.

Well now I'm even more confused about why my connection to my #OVHCloud dedicated. I've installed iperf 2 and 3 (the remote machine I have access to on a fast link, but also in the UK, only has 2 installed). I'm using three network locations for the tests:

  • Home is my local connection.
  • Remote is the machine I have access to on a different UK network.
  • The server is the one hosted with OVH in Canada.

And now I have the following data points:

  • iperf3 from my home to the server can happily do 100 Mb/s UDP.
  • iperf2 from the remote machine to the server can do more (it's on a faster network)
  • iperf3 locally with TCP starts slowly but usually manages to reach 100 Mb/s.
  • Wireguard from my home to the server struggles to get more than 2-3 Mb/s.
  • scp from my home to the server gets a similar speed.
  • scp from the remote machine to the server happily gets 100 Mb/s (probably more for a larger file, I tested only a 100MiB one).
  • If I run nc on the server on a random port and send the data to /dev/null, I can transfer at 100 Mb/s from home.
  • scp from my home to the remote machine.

So it looks as if something is specifically targeting ssh and wireguard traffic, somewhere between my ISP and OVH's Canadian connection.

Quand la vaste majorité des valeurs #tech se sont effondrées la semaine dernière... #OVHcloud a pris +45% sur la même période.

C'est à la fois :

👉 Rassurant, car l'idée d'une urgence à s'équiper d'offres cloud / tech européennes semble faire son chemin jusque dans les milieux financiers

I removed, OVH from my list of recommended providers.

Why?

OVH previously only resold servers in the United States, with their datacenters and business offices overseas in France. Today, OVH is under direct Us Jurisdiction, even redirecting their traffic to their American site us.ovhcloud.com and their terms of services outline an address in the USA, plus they're hiring for their own datacenter in the USA, and lastly in the footer of the website it now reads, "Copyright ©2025 OVH US LLC"
