Repeated blog article rss feed

[a2n]

I subscribe the blog rss feed, there is a strange phenomenon since 2018-09, that is, an article rss feed repeats in random period, its title is "In a previous article , we explored how HTTP/2 dramatically increases network efficiency and enables real-time communic...", and links to https://grpc.io//2018/11/27/2018-08-20-grpc-on-http2.html

I think this is because the title was messed up, and so github just changed it to the modified date of the file.
