A particularly nasty hurricane could level Florida and continue on to do damage to Virginia as well, but Virginia is more structural damage resistant (peak winds drop rapidly inland). However, odds are low. As someone who does DR and IT dependability professionally, you get the level of redundancy you can reasonably pay for. Nothing can be 100% sure not to have failures. You're more likely to have outages and lose data due to people than anything else. Software failures less than that, Hardware failures less than that. Environment is statistically the least, below 10%. Very complex environments with multiple sites and failover generally don't have single-cause attributable outages, though in rare cases engineering and design missed something and a single point of failure remains and fails. Everything only being in Florida was a major risk factor, but we're long past that. -- -george william herbert george.herb...@gmail.com _______________________________________________ foundation-l mailing list foundation-l@lists.wikimedia.org Unsubscribe: https://lists.wikimedia.org/mailman/listinfo/foundation-l
