Ireland Routing / Internet Issues

Is anyone else in Ireland having internet connection issues? The IPv4 network seems to have fallen over...

All my uptime alerts have been triggered, but they are on EC2, and the sites are in HP Cloud, 2 datacenters in Dublin, and in a 3rd level institute.

Google (and associated services), imgur and facebook all are intermittent over IPv4, but all fine over IPv6.

Anyone else see this?
