Missing phoronix.com feed

Phoronix.com is missing from my list of feeds.
In newsblur activities when I follow “You subscribed to Phoronix.” it’s this address newsblur.com/site/2013972/ and message “Oh no! There was an error!”.
In my browser history I see this address newsblur.com/site/5171497/phoronix-61-31.12.2013. and when following same error as above.
Feed isn’t on 64 sites list. On top of the list it’s indicated 47/48, all (47) sites in list are ON so 1 feed is missing from list.
