I had two technical problems the last few days. Stop reading here and go back to playing your guitar, if you are not interested in the technical details...:)
1. - I have had some problems with my dns-servers. They were located at a fairly unstable branch of the Internet. When they were offline for more than a few hours, people are starting to get problems accessing chordie. They get errors like "domain name not found". I decided to move them (this actually takes 24-36 hours), and it should really happen silently. However it failed terrible when the owner of the new dns-server turned out to have a policy where they are directing all new customers to an ad-site for a few hour. A lot of people thought Chordie was hacked. However the move is complete now, and you can expect more stability in the future.
2. A disk was full yesterday, and the site was down for an hour. Many thanks to James for reporting this immediately. I was just on my way out when I noticed his message. If he had not sent it, the site would have been down for almost a day.
After moving to the new server about a year ago, things have been very stable. The only real problem has been the dns-servers, and that seems to be fixed now.
If you ever are unable to access the site, send a mail to admin@chordie.com.
