Possible BT routing issues but not sure...
Discussion
We have a BT Infinity business connection, with a Cisco 800 router / modem.
Yesterday, we were randomly losing connection to various sites, but this morning there's virtually no connectivity.
As an example - last night I could ping 8.8.8.8 but not 8.8.4.4 - so I rebooted the router - following which I could ping 8.8.4.4 but not 8.8.8.8 !!!
At the same time, some sites that were inaccessible suddenly became accessible - and previously accessible sites were no longer accessible.
This has to be a BT routing problem surely?
We have no custom routes on our router.
We have 3 different firewalls with multiple external IPs - all are displaying the same symptoms, so that rules out firewall issues.
Traceroute shows loss of connectivity at various points - but of course this is becoming increasingly difficult with so many ISP disabling ICMP on their routers.
Finally - the clincher - we called BT, but because we don't have a supported device, they can't help us.
So we're stuck without internet - and no apparent way of our ISP diagnosing it, as it's seemingly impossible to bypass the call center drone.
Does anybody know who I can escalate this to at BT, bypassing the drones?
TIA.

Doesn't have to be a BT router - any make will do.
BT were insisting on us plugging the originally supplied router back in, as it has a diagnostics port (which from what we can gather is simply a VLAN) - but we no longer have the originally supplied kit.In any case - we borrowed a modem last night, plugged it in for an hour, and the problems mysteriously went away...
The Cisco is back in service now and all seems fine - which is really quite odd.
