There is a problem with the Guild of One-Name Studies website. It has been unavailable for some days, reportedly owing to a problem with their internet service provider. Word is it's likely to be unavailable for a few more days.
Fortunately there are other ways to contact them:

A no doubt unintended benefit is finding a link to the BBC Radio 4 program Word of Mouth, on Surnames on the Facebook page. I was surprised it wasn't behind a UK firewall. It starts with the an interview with a person who would be a genealogist's nightmare.
