Google rolled out new Subversion - - which's about 3 times faster than they used to be. “To improve reliability, new service has a custom replication system based on Paxos algorithm. Whenever you make a change to your repository, new data is now copied to several different data centers before service reports that commit has succeeded. “One of the features of Subversion's HTTP-based protocol’s that anyone can browse repositories through normal web browser. Many open source projects hosted on Google Code use this feature to host websites for their project or post latest versions of their software. Latency for these pages’re much lower and international users will see a dramatic improvement. We also set appropriate caching headers, which can be manually controlled with google-cache-control Subversion property,” notes Google.
