For 1-2 weeks, pinging my DB server would take 1.4-12.0 secs for a round trip. As of 2-3 days ago, my ping times are down to 700-800ms. My site accesses the DB quite a bit, so it's running great, now, but when times go to 5+ ms, it gets ugly. It seems to happen in waves. Days of 2,000-10,000ms, then suddenly, a few days of <1,000ms. I am certain it has nothing to do with my code. It happens using phpMyAdmin and any other simple tools I've built to test it out. Any clues?
