I imported the following feed into theoldreader:

http://www.buchreport.de/index.php?id=5&type=100

It shows only two articles from early april but does not update. I tried to remove the abo and readded it but the behaviour is the same. It seems there are more feeds with this problem. Any insights would be helpful. Thanks in advance.

Furthermore: the feeds from

feeds.feedburner.com/myDealZ
and
chillmo.com/feed


are updated with heavy delays, which is somewhat counterproductive since the publish sales that often come with limited numbers and it is unfortunate if the news is shows hours later. Is there any chance that these will update more often in the future? (I know, no one has the server capacity of Google, but there the feeds updated almost instantly).

Thanks again for your help!

regards,
Xanathon

http://www.buchreport.de/index.php?id=5&type=100 does not seem to be a valid RSS feed. Please take a look at http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fwww.buchreport.de%2Findex.php%3Fid%3D5%26type%3D100

Feeds that are getting updated almost instantly are usually the ones supporting pubsubhubbub. These two feeds you are referring you are plain old RSS, so they will always have a delay.

Thanks for the quick reply.

The Buchreport-feed is displayed correctly in Google Reader, Feedly, Netvibes and some others I tested.

Well, as I said, the other two feeds were updated within minutes in Google Reader but sometimes it takes hours to see updates in theoldreader so I cannot believe that being them RSS feeds is the problem.

Thanks again.

I've experienced severely time-lagged feeds as well. It's not even a matter of minutes. Manually refreshing will turn up items that are already hours old.

Some of my feeds will not update even when manually refreshing them, for example: http://slog.thestranger.com/seattle/Rss.xml?category=21233
This feed posts a couple dozen times a day, yet even manually refreshing gets me nothing more recent than April 28th. I noticed the problem after importing all my feeds from Google Reader (where it worked fine), so unsubscribed and resubscribed manually. No dice.

I first noticed a problem when a feed suddenly had more than a dozen unread items. The oldest item was from three days ago even though I have been checking Old Reader a few times a day. I just noticed that another feed's most recent post is from 12 hours ago, but going to its site shows more than 20 posts since that time.

If this is how Old Reader is going to behave, then I might have to find another alternative to Google Reader.

A further problem with the Slog feed that I mentioned above, which hadn't updated since April 28th: since making that post, it has finally updated - starting with posts made the evening of May 7. It updated normally until the evening of May 9, and hasn't updated since. So it's not just a refresh-timing problem, it's a problem pulling posts at all. The feed shows no posts at all made between April 28th and May 7. And as I mentioned, the feed works just fine in Google Reader.

I have a related problem. Consider the feed http://nrc.nl/rss.php?n=np. About 200 posts a week are made and it supports pubsubhubbub. In TOR it is refreshed once or twice a day. According to the knowledge base this feed should be refreshed instantly (because of pubsubhubbub), but even without it, it should have a refresh rate of about 2*(200/7/24)=2.4 times an hour. Just as in the posts above: it works fine in Google Reader. What goes wrong?

ontophantoms, http://slog.thestranger.com/seattle/Rss.xml?category=21233 does not seem to be available from our servers - http://pastebin.com/PEyidePt - even though we can access it from our home connections. It looks like they have blocked the whole IP range of the ISP our servers are hosted in. There is nothing we can do about that, unfortunately.

sw5110, how would you expect us to investigate this if you have not even provided feed URL or ID?

rjsomeone, we are getting no pubsub notifications for http://nrc.nl/rss.php?n=np even though we are sending subscribe requests to the hub. You might want to subscribe to http://nrc.nl/rss.php instead, it seems to have identical content, but sends us pubsub notification properly.

Thanks for the quick reply, I'll change feeds! More a theoretical discussion now (or for my other feeds that do not support pubsub): why didn't this http://nrc.nl/rss.php?n=np feed get refreshed as often as I would expect given the ~200 posts a week?

rjsomeone, because we don't refresh feeds manually that often when we succeed in subscribing using pubsub. All pubsub feeds are only fetched every so often – 1-2 times a day – just in case there is something wrong with the hub (like in this case).

Ah, I sort of get it. Wouldn't it be more user-friendly to keep the refresh rate at twice the avg. post frequency if the algorithm determines that the pubsub data is faulty?

Thanks for the response. I contacted the site's webmaster about it and they would like to know what IP range your requests are coming from.

This was the one that did not update for three days:  http://www.whedonesque.com/rss.xml.php

This was the one that did not update for at least 12 hours:  http://feeds.boingboing.net/boingboing/iBag  The latest post from it is dated May 14th at 9:15AM, but on the website I see about 50 posts since then with the latest one being May 15th at 12:03PM.

http://www.cakewrecks.com/home/atom.xml does not show today's post (google reader shows it was posted six hours ago).

http://cuteoverload.com/feed/ is currently missing the latest post (from an hour ago according to google reader).

We have just tried subscribing to these feeds in our test account, and all of them seem to contain very fresh posts.

I seem to be having trouble with the Ars Technica feed (http://feeds.arstechnica.com/arstechnica/index?format=xml).  The site updates many times per day, but TOR doesn't seem to be updating it nearly that often.  Right now, the last time it updated was apparently yesterday (Wednesday) afternoon, grabbing the 25 articles that were in the feed at that moment, but those only go back as far as Tuesday morning.  The last article TOR had fetched before that was on Sunday evening, meaning that all of Monday's articles, plus a few from Tuesday morning, never showed up (a total of 22 items).  I know that they were in the feed, though, because they showed up on Google Reader.

This was the largest number of updates it's missed in one go, but it's not an isolated incident, because, over the past few weeks, it has repeatedly missed smaller handfuls of articles (ranging from about three to eleven at a time, from what I can see).  Any idea why TOR goes so long between updates to this feed, given that the site posts new items quite often throughout the day, so I would expect TOR to update it probably every half-hour or so?

Thanks.

TSN, for some reason we are not getting pubsub notifications from the hub for that feed.

We are working on some work arounds that will eliminate feed refresh delays even when hub is malfunctioning.

Okay, thanks.  Right at the moment, it's showing articles from this morning, so it's pretty up-to-date.  Maybe I'll try refreshing it manually if I see it falling behind again, until a solution is in place.

Hiya.. I'm the webmaster for thestranger.com, one of the sites having this problem, and we've heard from other readers having problems too.

The IP ranges you've listed here are massively broad, and there's no way we can whitelist such a huge list (over a million IP addresses!). Do you have any way to know more specifically what IPs your requests come from? Does The Old Reader use a specific User Agent string we can check for, at least?
