Sudden loss of speed (New Malden)

Anybody else on New Malden had a sudden loss of speed on their connection?

I'm now barely hitting 5Mbps.

Image from my samknows whitebox:

ok, I've switched to a different IP from my allocation and it's come back to full speed.

DDOS?

Re: Sudden loss of speed (New Malden)

Yeah, it's fixed, the order has been restored.

Many thanks for spiderplant (again!) for checking things out.

I only noticed because (slightly ironically) I was working on some changes to my project which measures network latency, and on my CI/CD server it was taking 3 minutes to check out the code.

I'm lucky if I can pull source from GitHub at more than a couple of hundred kilobytes a second.

Re: Sudden loss of speed (New Malden)

I'm guessing this is a bit of a problem.



Now I don't know whether this is specific to me or related to the issue that occurred last week (when this problem started) that was a low power fault that affected multiple customers which an engineer resolved by reseating a cable somewhere.

Re: Sudden loss of speed (New Malden)

That looks fine to me. Last week's fibre fault wouldn't cause low levels on your cable, and doesn't appear to have come back again. No more tickets raised since 27/04.

Are you still experiencing slow speeds?

I haven't used the computer since this morning, but just ran some SamKnows RealSpeed tests and speedtest.net tests and it appears to be back to normal now. Single-threaded performance though is poor.

I haven't logged into my office machine (RDP over SSH tunnel), I'll try tomorrow to see if the laggyness has gone away if the speeds are still normal.
