Planet Lotus not picking up Christopher's feed

by Volker Weber


Since I am subscribed to Christopher Linfoot's feed (here on Feedburner), at first I did not miss anything. But it appears Planet Lotus has not seen any updates from him in the last two days. So you may want to visit his site directly. He always has interesting things to say.


The same is true for my site :(

missing my post, too ;-)

@vowe, feedburnner is being cached somewhere. I've been on it for days. It's happening periodically with all feedburner accounts. Everyone/anyone is more then welcome to send me their non FB feeds to use in the interm.

@Mac, feedburner as well?

@Alexander, we've spoken, I believe it's that fact that you've added google analytics code in your content. Bet you a beer Sunday night at Lotusphere that that is the cause.

Yancy, if I call Feedburner, it has all postings.

Everybody else, let this be a warning not to give up hosting of your feed to a service.

Two possibilities:

1. There is a caching proxy server (possibly transparent) somewhere upstream from PL. Proxy server is not fetching updated feeds but instead returning stale feeds, so PL sees no new content.

2. FB is rate limiting requests from PL's aggregator.

The latter seems unlikely as other aggregators (e.g. Bloglines) have no difficulty, yet probably poll a far greater number of FB feeds.

A caching proxy that does not update in two days?

Volker Weber, 2008-09-03

The lag is typically a few hours, not two days.

Chris Linfoot, 2008-09-03

@Yancy: The adsense code has always been there (to be honest, I had not the time to figure out how to remove it from the feed). And the other posts are there and contain the code,too.

So I hope for a free beer at Lotusphere ;-) Hope I will be there Sunday night...

@Chris, is there anyway to test for a transparent caching proxy server? I just got off the phone with GoDaddy, they do not have any caching servers in-between their Dedicated Servers and the WWW.

Yancy Lent, 2008-09-03

@Alexander, be sure to catch me Sunday night pool side at the random Open Bar of your choice ;). I'll look into your feed further.

Yancy Lent, 2008-09-03

I had a caching oddity with PL a few weeks back, but I am certain it was something strange with the relevant Domino view that underlies my RSS feed rather than anything intrinsic to PL (the two main RSS validators refused to “see” the updated RSS feed too).

Might be worth looking into? Bottom line is I think Domino was serving a 304 when it shouldn’t have (assuming it can send a 304: I’m not convinced).

Notice at 7:59p a flood of feeds from FB came in at once. Both Mac and Chris... More headaches to follow with FB for sure.

Yancy Lent, 2008-09-04

@Yancy - if you can install and run something like the Sam Spade safe browser on the same server as is running PL and then use it to pull an FB feed, you should be able to see from the http headers (which are visible in the SS safe browser) what upstream agent handled the request. The Live Headers extenstion for Firefox does something similar though I find it more cumbersome to use.

@Ben - Domino can only send a 302 or, in D8+ only, a 301.

I'll just keep on relying on Bloglines instead of reading PlanetLotus...

Lars Berntrop-Bos, 2008-09-04

There's a distinct diurnal pattern to the failures.

Posts in the morning in the UK (the small hours where PL lives) are picked up almost instantly. Posts later in the day, after America has woken up, are ignored for hours at a stretch. PL itself also gets very slow.

Could just be a load thing?

Chris Linfoot, 2008-09-04

As a follow up, I see that post from yesterday at 8:50AM made it onto PL yesterday at 7:59PM.

Mac Guidera, 2008-09-04

@Chris, the load will surely ease with @Lars no longer reading the site.

You are the first to report an actual slowdown of the site later in the day. It's surprising because the front page is decoupled from the back-end database and is completely .html You are doing a pure download of a compressed (at the server) text file. There is not processing of data going on unless you go to a second level page. If its statcounter or google analytics hanging that is unfortunate but if its just the downloading, yikes. Do you have a estimate of the time differences, morning v night? Does anyone lease experience this?

Yancy Lent, 2008-09-04

@Yancy - its the blog widget that bogs down - can be several seconds - and PL off site links which all go via your redirector so you can count the clicks. Not the home page itself.
