Fibre 500 running at 150

[NXG]

Hi,

I have Sky Fibre 500 but over the last couple of days I've noticed it being quite slow. Two speedtest sites report throughput of only 140-150Mbps. Sky tests show I should be getting >400. I've checked throughput up to the Sky router and all is well with Gigabit connections. I'm a network engineer by way of full disclosure so I know how to run tests. It appears my link is being throttled or shaped somewhere. Anyone else had this issue?

Thanks.

@NXG as I assume you are aware the only reliable speed test on a full fibre connection is one run with a single device on the network which is connected by a direct gigabit ethernet cable. If that applies it is worth forcing a disconnection by powering down the router and seing if the speed changes. If it doesn't call Sky and report the issue their network team will check the issue.

There is no proof Sky throttle or "shape" connections but faults have been known and forcing a connection change can switch a connection at Sky's end  from a port with issues to a good one. Theoretically you can have issues with contention as your Openrea ch fibre connection shares a roughly 2Gb/s fibre to the exchange from the local distribtion point with up to 31 other customers however in practice that is very rare but y=that is how Openreach's GPON system works.

Yes, fully aware; not my first rodeo. My device is on Gigabit Ethernet. Calling Sky and speaking to anything other than an IVR, let alone a human that can go beyond the scripted "turn it off and on again" is a challenge.

FYI, Sky have to throttle/shape Gigabit fibre links to the CDR the customer has bought else OLTs with only a couple of ONTs would be getting all their birthdays at once.
