What is an acceptable uptime on router

After many Openreach visits I now have a functional Sky Fibre unlimited connection with Sky Q box.

I continue to monitor the connection, while it is OK I am still getting 1 or 2 dropouts per day. I cannot see a pattern. Is this acceptable, if there a minimum acceptable uptime for Sky Broadband ?

Uptime, as in router crashes falls over and cannot be accessed at all? Should be many many weeks for that.

If the dropouts are resyncs of the VDSL2 connection then 1 or 2 a day is likely to just wait on the DLM system to intervene and reduce speeds, add error correction etc to reduce the level of these.

So is there a documented minimum up time? NO

Are you interpreting your BQM graph correctly?
The red spikes of packet loss are not going all of the way to the bottom, so it doesn't appear that you are re-syncing (your router logs will tell you either way).

Read: https://www.thinkbroadband.com/faq/broadband-quality...
Under heading "What should I see if my connection is idle and running well?":

The BQM will usually show a red line that is one or two pixels wide stretching from the top to the bottom of the graph if a router is re-syncing.

and further information under heading "Re-sync".

The router log shows these red dips correspond to resyncs of the VDSL2 connection. It takes just over 60 secs to resync. Perhaps the polling time is on the monitor is on the same timescale so it does not show full drop out.

I need to read up on re-sync... is it common ? I have an option of another OpenReach visit tomorrow , is it worth it ?

Just to add the downstream noise margin this morning is 8.3dB for my 40Mb connection.
Is this a bit high, I am close to the cabinet. Does Sky have a target noise margin for their Fibre Unlimited offering ?

BQM polls once a second and each pixel on graph is 100 seconds, so if resyncing in 60 seconds that is fairly fast for VDSL2 (can take two minutes)

A resync a day is something you don't want, but its not uncommon. Reasons such as interference from local equipment in the home, and presence of extension wiring picking up the noise all can increase the amount of resyncs.
