The hosting provider I use is generally good. The pages load quickly. There are no brown outs where my site goes down for a few seconds or minutes. But when it does go down, it goes down for 6-8 hours. The problem is they run their drives too close to full capacity so when someone uses up a lot of diskspace all of a sudden, the file system corrupts and they have to shut everything down for a multi-hour FSCK. This has happened 3 times in the last 6 months. Which means their uptime is still 99.9%+. The websites that keep track of hosting uptime rate them as better than the industry average. Which is still hard to take when your site is down for 6 hours straight. I rather it go down for a minute here an there more frequently.
Is this reasonable uptime or should I shop for another provider?
