I get about hit with this and about five other speedera IPs. It happens about every two minutes for each one. Is this a spider or something else?

Welcome to WebmasterWorld!

Speedera appears to be a content delivery, management and cacheing service...

Perhaps they are keeping tabs on your server to see what its uptime stats are? Or cacheing the page? The bot does not appear to belong to a SE spider.
