August was not our best month.
We did a bit better than 99.3% uptime. Almost all of the downtime is due to a recurring, as-yet-unsolved problem we are having with our Oracle database platform. The primary symptom is that the database platform stops fielding queries for about 5-15 minutes, which disables our production web site. The platform does this about 30-45 minutes AFTER it has finished a full export using the Oracle datapump system.
Because our existing Oracle hardware is old and has a relatively slow disk I/O system, we're going to try to solve this problem by throwing hardware at it. For well under $10k we can replace our five-year-old hardware with something much newer. Goodbye RAID-5 SCSI, hello SSD.
