The twitter card validator says it can’t find my site, www.metatest.nl , anyone got this same problem with his/her site?
Hi there. We’ve sometimes seen this because some web hosts block our IP addresses of our Caching crawlers.
If possible, I would pass this on to your hosting site, and ask them to ensure they’re not blocking our IPs:
