I use the Twitter API to post article titles followed by a link to the article, and sometimes a repeat of the domain name if I think Twitter is going to tinyurl me. Generaly Twitter converts URLs with characters it doesn't like [^A-Za-z0-9.:/], or URLs in tweets that are too long, to tinyurls.
However, this evening, none of the URLs I posted were converted to tinyurls. Not even the ones with characters Twitter doesn't like, and not the one that was too long. Here are the status updates I expected to be tinyurled, followed by a link to the individual tweet as it appeared on Twitter. The first 3 contain bad characters (underscores or commas), but are fewer than 140 chars: GA approves more charter schools http://www.ajc.com/metro/content/metro/stories/2009/04/01/georgia_charter_school.html (ajc.com) http://twitter.com/GeorgiaLogCabin/status/1436345350 Obama's tax pledge up in smoke http://news.yahoo.com/s/ap/20090401/ap_on_go_pr_wh/obama_tax_promise (news.yahoo.com) http://twitter.com/GeorgiaLogCabin/status/1436192094 Sweden recognizes marriage equality http://www.theaustralian.news.com.au/story/0,25197,25277939-12335,00.html (theaustralian.news.com.au) http://twitter.com/GeorgiaLogCabin/status/1436147039 This one has bad characters (dashes) and is longer than 140 chars: Obama wants anti-gay advisor http://www.usnews.com/blogs/god-and-country/2009/03/31/exclusive-former-nfl-coach-tony-dungy-invited-to-join-white-house-faith-council.html (usnews.com) http://twitter.com/GeorgiaLogCabin/status/1436319188 That last one shows on http://twitter.com/GeorgiaLogCabin with a truncated URL that causes it to link to a broken story. However, on the individual Tweet link above, the URL is not truncated and works fine... So I have one main question with a few possible answers: Q: What happened to Twitter's auto-tinyurl convert? Possible answers? A1: Tinyurl just happened to be down during the time I was posting updates, so Twitter couldn't request tinyurls and used my long ones (though other people's tweets before, during and after mine appear to be tinyurled as normal.) A2: Twitter just this evening stopped tinyurl-ing my tweets, but not anybody else's (at least not anyone I happen to follow.) A3: Some Twitter bug nobody's aware of (I searched the FAQs, this message board, and via Google and didn't find anyone else with this particular issue.) A4: Some other reason? Any ideas?
