Hmmm – that must be related to the round-robin DNS/multiple caches, although they *should* be handling that internally regardless :-/

..although I still get the flip/flop effect when a post appears, and then disappears the next time my reader refreshes the feed, only to have it come back on the following refresh – presumably due to the two instances having different caches – I guess that’s only an issue until you get the filesystem stuff working

I’ll look forward to reading your write-up of your experiences with S3

Unfortunately I’m yet to finalize implementation of S3DFS (a distributed filesystem backed by Amazon S3), which would give me the shared cache repository that I wanted to use for multiple servers, but I’m hoping that some of the changes I’ve just rolled out will help.

Update on that coming momentarily.

Thanks

The two servers thing seems likely – my feed seems to randomly flip-flop between a feed last updated on the 15th and one last updated on the 16th – looks like the two server instances aren’t in sync with each other (or the universe in general!)

Hey benjymous – thanks for the heads up. I was starting to notice a few issues myself, but then it will update almost randomly, but then fall back behind again.

I’m looking into what’s causing this. It might be related to the fact that I actually have 2 servers running FeedBlendr now, in a round-robin load balanced configuration.

I’ll post an update on the blog once I figure out what’s going on (and fix it

Thanks.

*update*

It’s now displaying posts from yesterday morning, so still stale, but something’s working, somewhere, I guess

Hi, it’s me again – My blend seems to be stale again (nothing new since 7pm two days ago)
