We are aware of an IPv6 issue on the network following on from a firmware upgrade within our core last night.
We have been working with the hardware vendor to resolve the issue but while this is ongoing , we have been reverting back to a previous version of firmware and moving connections between gateways.
Some users will experience a graceful PPP drop of around 5 seconds while there connection re-authenticates.
We do apologise for any inconvenicance
UPDATE01
LNS02, LNS03, LNS04 have been reverted and IPv6 connectivity has been restored.
LNS01 has been isolated for testing. Anyone experiencing slow DNS lookups or applications now loading are advised to reboot there router which will be routed to one of the other gateways with the fix applied.
UPDATE02
Further issues where identified with IPv6 within our core network (Broadband facing) Work to resolve this has now completed and IPv6 should now be fully operational again across all gateways.
