I wasn't aware of it when I posted yesterday, but apparently Amazon's new SLA for S3 followed on the heels of a similar offer from Nirvanix, and is due to be followed shortly by an even more aggressive offer from Flexiscale touting 99.95% uptime; this all from Nick Carr at Roughtype.

Not five nines, but getting there.

• Amazon S3 makes European sites available
• Amazon EC2 service out of beta
