We are experiencing some network issues. The issue is with the core routers, network engineers are assessing the issue at present.
UPDATE: The network problem has been resolved. The problem was caused by a failure in one of our primary routers. This took some time to diagnose due to its nature, but once we had done so we determined the problem to be with the management blade within the router. This was replaced using one of our emergency units, and the issue appeared to resolve. Unfortunately, approximately 15 minutes later we were once again alerted by our monitoring systems to further problems.
After further diagnosis, we determined the issue to be with the chassis of the router, hence the problem recurring after the replacement blade had been installed and configured.
We have now completely replaced the router with a spare unit we maintain should such an occasion ever occur, and the network now appears stable. We are of course continuing to monitor the situation closely, but we have every confidence that full stability should now ensue.
The failed unit will now be inspected by our network administration team to try and identify a more specific cause of the failure.
Please accept our apologies for any inconvenience that this issue has caused.
