We have reports of problems with the Google Custom Search Engine (CSE). Custom search is now used by many websites to help people to find and navigate around their site. It is a free service provided by Google. However, today it has failed.
Many websites are now left without a search function on their sites. This breaks the usability rules – people need to be able to search around a site, especially when there are thousands of pages.
Many people chose to use Google CSE as it is free to use and provides better results than many search engines that are built into a CMS (content management system).
Hopefully Google custom search will be running again very soon.
