Over the last months, China and India have both moved up the list, and it may be anticipated that they will continue to rise. Some countries use 'edu' to signify educational establishments whilst others use 'ac' for academic organisations. A few countries use both.
There are other lists of chemistry departments, notably ChemDex run by Mark Winter at Sheffield Unversity and the WWW virtual library hosted at Liverpool University as Links for Chemists and run by Michael Barker. All the main indexes of this type are based in the UK, and I am not aware of current competitors in other countries. Both of these have a broader scope than c2k, including many companies as well as chemistry departments. Currently, they include fewer chemistry departments than c2k. Other resources, such as PsiGate have fewer links, but each one has been evaluated and reviewed.
Google is so effective that the need for lists of chemistry departments and chemists may have diminished. However, there are questions for which Google cannot compete. For example, in order to find out about a chemist or department with a common name, or to be sure that a representative sample of departments have been covered in a particular area, or to compare the importance of chemistry in universities in different countries, a Google answer is hard to interpret, and a reasonably complete and up to date list is more useful.
