Having some trouble with my blog yesterday where a few readers were saying they saw no theme or images, basically anything served from MaxCDN on cdn.dragonblogger.com was being served. It was like there is some sort of blacklist or filter in the CDN that prevented it from serving files to these readers.
I have temporarily disabled the CDN portion of W3 Total Cache on DragonBlogger.com until I can figure out the issue, but I did purge all cache and will have the users directly hit cdn.dragonblogger.com to see if they can see any content being served from there or not.
I may have to open a case with MaxCDN to figure out the cause, I haven’t seen this happen except when my hosting provider changed my IP and the CDN needed to sync with a new IP but this isn’t the case this time and it is for a limited user set.
