Due to shortage of disk space, we have stopped NCBI/EBI SRA data mirroring since April, 2017. In this March, the NIG supercomputer was replaced and storage capacity was increased, so we have resumed the mirroring since June. You may check newly mirrored SRA runs in the published data of sralist in ftp://ftp.ddbj.nig.ac.jp/ddbj_database/dra/meta/list. SRA data growth.
