API posts/update often returns no response

Hi,

I was doing some testing tonight and found that the API requests
"posts/update" were often not giving me any XML. Further testing
showed that it's most like to fail if I wait a few minutes -- the
first response I get has no XML. But subsequent requests sent
immediately this tend to succeed.

In the following run of 14 posts/update requests made via curl, note
that numbers 1 and 11 failed. The others succeeded.

It seems that the failures always occur with server fe07, but
sometimes fe07 works. Is something broken in Yahoo!-land?

I have been experiencing similar issues with XML sometimes not being
returned. I think it is with the call "posts/all". This seems to
have started yesterday March 4th. I haven't traced it to a particular
server.

Hi all,

Looks like there might be some problems on our side here.
In the case where you get no xml response back you should be getting an HTTP response code of 500, but I agree that is not ideal (some xml that you can see and parse would be much better). We're working on changing that.

In addition, we've ironed out some other issues and while you still might get this empty response, it should be much less frequent now.

Well, if it would give me some useful information which I could
display to the user regarding why it failed, that would be
worthwhile. But if it's just going to say "Sorry, request could not
handled", well, 500 is good enough. And it doesn't require me to add
any more code to my app :))

It seems about the same to me, Chris. Server fe07 is still the
culprit. I just ran another test and got:

Server fe07 Worked properly: 1/4 Score: 25%
Other servers Worked properly: 5/5 Score: 100%

The test is very easy to do....

Hi again,

I looked into this and it does indeed happen with "posts/update". It
is still happening frequently.

It seems to just return most of the time:



Also it does not seem to be returning a 500 error when it does this.

This confirms what Jerry found previously.

It appears that the only reliable way to get around this is to call
"posts/update" and then try again soon afterwards. If you back off
for another 30 minutes, then you will likely get this problem again.

This is affecting the users of my app WebnoteHappy. I could issue a
fix that calls "posts/update" twice in quick succession, but this does
not seem like a good long term solution.

Any suggestions?

Thanks,
Louie

Hi,

This server was having some problems it seems, so we've removed it. Things should be back to normal. Apologies for the inconvenience, and thanks for reporting it.

Hi Chris Draycott,

I am working on a project for a class. I attempted to download bookmark
data as a JSON feed. I received the same error as described in this thread.
The response I received from the url was the following:



I verified that my code works with other feeds. So, I guess the problem
others experienced has reappeared. If you could help me with this, I would
greatly appreciate it.

Thanks,

progmanos
