On the BT forum some other web design agencies were having the same problem, and not just with BT, Virgin and Orange seem to be also effected according to some reports. While the issue is beyond the control of the people managing the DNS records for the client we could be held responsible for the downtime of our clients sites.

While this is a temporary issue it still affects area of website ranking, businesses that rely on their website for income and the confusion of Google knowing if the website has been taken down.

Hopefully, whoever caused the problem within the nameservers, the issue will be resolved as soon as possible but I am quite shocked how this problem has been kept quiet and expecting us to ignore the problem not just for the developers but for Internet users.

Anyway during my work as a web developer I find it really important to understand the terminology on managing websites especially if you run your own server. This covers the importance of A records, MX records, sub domain structure and zones.

Wikipedia is an excellent source of information regarding the DNS structure. which I advise any freelancer to look up because client will always come to you regarding domain transfers, emails not working and in a lot of cases a domain name is registered with someone completely different to the hosting.
