tr.imPopular URL-shortening service announced yesterday that it has restored its service and has reopened its website. After two days. What the..?

Nambu,'s parent company, had announced last weekend that it was closing the service (see 'URL shortener closes, blames Twitter'). But a message on the blog now says the service is back in business, although its future remains murky:

"We have restored, and re-opened its website. We have been absolutely overwhelmed by the popular response, and the countless public and private appeals I have received to keep alive...

"Nambu will keep operating going forward, indefinitely, while we continue to consider our options in regards to's future.""

Internet news and reviews's resurrection means that shortened links in thousands of Twitter posts, emails, and text messages will continue to work into next year. The site's URL-redirection service was slated to last until the end of 2009, and its future was unclear beyond that.

Nambu's sudden change of heart is surprising. Earlier the company had stated that a shutdown was necessary because the service was a financial drain. Network costs are expensive, after all, and Nambu couldn't find a way to monetize

Today's blog post also took a few shots at Twitter, which Nambu says is making it difficult for to stay in business:

"Twitter has stacked the URL shortening business opportunity overwhelmingly in's favour, as currently operates. This is not whining, as some have suggested, but a simple reality. If we post a link to this blog article by its title Twitter switches our URL to a URL.

" has a monopoly position that cannot be challenged with reasonable investment or innovation unless Twitter offers choice. This is a basic reality of challenging monopolies. has deep personal connections and agreements with Twitter that we simply cannot compete with. And it is our humble opinion that this type of favoritism will become an issue for all Twitter developers."

Nambu says the shutdown was not a public relations stunt.
