Our upstream provider has observed some problems with one of their core network devices:

We have observed a short outage on one of our core routers within London. Initial investigations are indicating that this was caused by a line card reboot. The router is currently stable, but under close monitoring. Further investigations are ongoing into the underlying cause.

We are treating this issue as a high priority within our organisation and will keep you updated on the actions being taken.
