Yesterday we received a great number of calls from customers unable to connect to services hosted on the Web Wiz network.
The cause was due to a worldwide outage that affected Cisco BGP
Routers globally when their routing tables reached their limits causing
outages to many ISP's and organisations.
The pages below on ITProPortal and The Telegraph have more detailed
information on the worldwide outage which also affected BT, Virgin,
Comcast, eBay, Amazon and many others:-

While our own Web Wiz network was not affected as we are not using
Cisco Routers our upstream providers were affected and we saw up to a
40% drop in traffic to our network.
