We apologize for the extended downtime that we had over the last three days. Our host has been subjected to a massive DDOS attack. Our mistake was in not religiously backing up this site (partly because of the difficulty of the backup process). We are going to come up with better backup practices in place for this site so that this can be live immediately at another location (even if only in a read-only mode) if the main host goes down. Thank you for your understanding.
