Heres the situation, I recently setup a few of my sites on a a CDN (specifically MediaTemple's ProCDN via Edgecast). Setup went perfectly normal but a couple of days later I notice this: (15K a day Average to 600K)
Now my domains / cdn is setup like so:
- I have custom nameservers for digitaldawn.net
- All supplementary domains point to these nameservers
- All supplementary domains have cnames setup to cdn.domain.com
- These cnames point to the Edgecast Origins ie. http://wpc.XXXX.edgecastcdn.net/XXXXXX
- The edgecast origins themselves grab content from http://www.domain.com:80. ie. http://cdn.domain.com/an-image.jpg will be the content distributed version of http://www.domain.com/an-image.jpg
Firstly, would my setup account for this excessive increase in DNS queries? (The sites that have CDNS setup currently get minimal visitors (Probably less than 10 per day)).
Secondly, providing this is perfectly normal, is there any way to sidestep this? I have 10Million managed queries through DNS Made easy and at the current rate I'm going to be up a certain creek without a paddle...
I think I can sidestep half of it by hosting each domain on a static IP and setting the origins to static IP addresses, however this is far from ideal as I have quite a few sites. Are there any other options?
