The aprs.fi service might have some small service breaks during the following few days. I'm upgrading the master server with 4*1TB disks (RAID10, 2TB usable capacity) and doing some other upgrades while I'm at it (including but not limited to the new operating system kernel, switching filesystems, LVM, database engine upgrade, etc). The first two disks already went in tonight and replaced half of the old ones, and the process will continue with data migration from the old disks to the new ones.
The first reboot (due to kernel upgrade) will be on Wednesday morning (around 0600 UTC probably). The web service should keep on running happily, but if the reboot will only take a short while, I probably won't bother to move the APRS data collection master function to the second server during the reboot, and some data will be lost during the boot.
Sorry for the trouble!
