Note that this SIAM logs directory contains many node2* files - each of these is created when the MMC reboots and SIAM starts. We noted that MMC begain rebooting repeatedly in mid-February, based on MARS hydrophone data. The first February node2 file is node2.201602182019, and then many more at 8 minute intervals. The last of these reboot files is node2.201602291857, i.e. on February 29 at 18:57 UTC - i.e. 11 days later.  - Tom O'Reilly
