TweetLater's Twitter API Issue – Explanation and Status

Update Wednesday, 11:17 PM EST: Fingers crossed. It looks as if the Twitter API issue has been solved.
Around last week Wednesday (March 25) we started noticing an increasing number of Twitter API calls getting an HTTP response code of 0 from the PHP cURL call to the API.

On Friday (March 27) the issue reached such proportions that we submitted a Twitter API issue. It was clear at that point that it wasn’t just a temporary glitch in the matrix.

Initially, the Twitter folks thought the issue was a networking problem on our side of the fence, which is quite understandable.

We, with the help of our hosting provider’s technicians, ran tests to troubleshoot the issue.

On Saturday morning we ran conclusive tests that showed the following:

  • Calls to the Twitter Search API and to any other web site went through without any issue.
  • Calls to the Twitter API went through sometimes, and other times received a Connection Refused, which resulted in the HTTP response code of 0 in the PHP cURL call.

Those tests showed that it was not a networking issue on our side, because only calls to the Twitter API experienced the problem.

Since it was weekend, not much further could be done at that point. We sent through the details to Twitter.

On Monday Twitter further investigated and determined that the issue was not with the site rate limit of TweetLater. We were well within the 20,000 API calls per hour limit.

The logical conclusion was that something somewhere on the Twitter network is (seemingly) randomly blocking API calls from our IP address. This could be a switch, router, firewall, etc.

Currently the Twitter operations staff and hosting provider technicians are investigating to see if they can pinpoint the problem.

There is unfortunately no time to resolution yet, until such time that they can actually pinpoint the root cause of the problem.

We’ll update this post with new information as it becomes available.

We sincerely apologize for the inconvenience, but please understand that the problem is out of our hands.

    Once processing resumes, the system will pick up new followers that followed you since the last time your account was checked. That you can see when you click the Auto Stats menu tab.

    Yeah Twitter has definitely been slow.The software that I've written that auto-tweets 24/7 is still going strong though – hopefully that doesn't get affected soon.

    It would be great if this got resolved ASAP, because I'm having to spend about 7 hours a day manually doing what Tweetlater usually does in the background for the Twitter accounts I manage for my job.And the whole “her having to pay for 7 hours a day of my time to do these tasks” thing is KIND of putting a dent in my campaign to get my boss to sign up for Tweetlater's Pro service. :/

    I am new to TweetLater. On some of my tweets I see a white circle with a black square in the middle. Is this an indication that the tweet failed?

    Well I'm not sure what API is but I'm guessing that it has something to do with why I cannot set up my Tweetlater account huh? Any idea on how much longer this will take?

    Thanks!So, is there any indication on my screens of which tweets are making it through and which ones are not?

    I noticed that my automatic replies to people who follow me stopped working on the 27/28 of March. I see a few coming through every once in a while. Is this a symptom of the issues you mentioned here? Will it be remedied when this issue is solved?

    I left the recurrence box empty on all my tweets and yet many of them are showing up with the little dots saying they have reached their recurrence limit. Why would that be? Also, both my “spinnable” tweets were disabled. Could this Twitter issue be the reason for these issues?Love Your Product,ShellyB
