We've been having recurring problems with internet outages, mostly lasting 5-15 minutes but sometimes hours or more. Often by the time I call through to tech support it's already working again. I've called several times but no one seems to be able to get through to the root cause of this issue.
The modem is in bridge mode. During the outage, the modem still thinks the connection is OK (all LEDs normal). If I load the DOCSIS status page however, I see that the downstream SNR has dropped and the upstream power levels are significantly higher when the connection is down. T3 timeout counter and correctables / uncorrectables are growing rapidly.
Here is what the status page looks like when I have no connectivity:
and 10 minutes later, it's working fine again:
If I reboot the modem during the outage, it gets stuck at acquiring US until the signal is back to normal.
Here's a graph showing my connection stability this morning - there have been three of these short outages so far (times are UTC).
Sometimes the modem requires a reboot before the connection is restored, but usually it comes back by itself. The modem is connected to the standard two way splitter supplied by Ziggo, on the other outlet is the TV, no other devices / spitters anywhere.
Any idea what I should be looking at? Does the drop in SNR and increased upstream power level indicate an issue on the cable network itself?

Okey, unfortunately you still seem to be having issues though so I think its time to request a Ziggo Network Technician.
