Hi,
We spotted some domains (c2m1u9.bbc.clfoundation.co.uk, tgu5b6.bbc.clfoundation.co.uk) which point to another IP (82.146.45.150) than your main site (
www.clfoundation.co.uk -> 94.136.40.103). This is highly suspicious and suggests a DNS hijack (either because of an unsecure server, or the credentials to your DNS leaked).
Let us know once you have resolved the issue (PM me) and I will unblock your domain
.
