It seems that the Rachel & Miles X-Plain the X-Men feed is no longer being parsed properly: http://www.rachelandmiles.com/xmen/?feed=rss2
It worked up until the most recent post on Aug. 5th, as I can still see the Aug. 3rd posts in my iPad and Android NewsBlur apps.
Looks like the feed is timing out, as its huuuuge. Also, it doesn’t validate. https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fwww.rachelandmiles.com%2Fxmen%2F%3Ffeed%3Dr…
NewsBlur processes the average feed in less than 1 second. If a feed takes > 20 seconds, it times out. That’s what the 505 Timeout means in Statistics (right click the feed).
I would email them and ask for a max of 25 items in their feeds.
Thanks for the quick reply! I will reach out to their web admin.
