Recently, the JMA Data Distribution System (JDDS) has been experiencing heavy traffic due to increase of the number of accesses. Making multiple connections or maintaining a long-term connection impose an excessive load on the server and interfere with normal server operation. So please refrain from making multiple connections and maintaining a long-term connection when downloading the data.
Regarding maximum connection time, we kindly ask users to limit to 12 hours per day in total.

We appreciate your cooperation in reducing server load.
