We have a custom RSS reader that is used to gather feeds from members who submit their sites for listing on a page of our own.
It is written on classic ASP/VBScript and uses MSXML2.ServerXMLHTTP.6.0, and has been working fine up until today apparently.
Today, it has been unable to get any feeds from blogs on WordPress.com. It returns the following error:
"msxml6.dll error '80072f78'
The server returned an invalid or unrecognized response"
It works for any WordPress site not hosted on WordPress.com. For example, I can check our own WordPress site, which is updated to the latest version (or so it reports). I can also go to the RSS URLs directly, and they open fine in my browser. Our RSS reader has no problems with any Blogspot sites.
So, I'm wondering:
Is it a temporary access problem? (Tomorrow will tell perhaps.)
Have there been updates to WordPress.com that might affect the RSS feeds?
Would our site somehow be blocked from checking the feeds? (I've checked at least 5 or 6, so it's not like 1 user blocking us.)
