9ox.net URL shortener closed

Post date: Mar 25, 2015 5:39:41 PM

Here's just the about page from the site as memory.

9ox.net credits, about, info


Do you hate long short urls like http://bit.ly/hUMuOq

or http://tinyurl.com/5wrvrpp which are short in theory,

but totally impossible to remember!

9ox.net solves your problem. We provide really tiny urls.

We can keep urls short because our urls expire

30 days after last visit or 365 days after creation.

Change log

2015.03.25 Service closed down, because Google closed Master/Slave datastore

2013.12.22 Version 4.10 released, service disabled

Service is disabled for non onion urls. .onion urls do still work.

Because I simply don't have time to maintain this

project. Deal with potential abuse etc. Otherwise I have been very

happy with Google App Engine and it's reliability and performance.

It was good as long as it lasted. - Thank you.

Lot of tuning with Unicode urls, solution still isn't

another of my virtual servers, using uWSGI and Nginx.

JavaScript based spam checking activated. It also releases

server resources, because if JS is not evaluated from create

page database won't be accessed at all.

Frontpage is now fully cacheable, earlier GAE sent permanent

redirect but with no-cache tag. It's quite pointless afaik.

Now it's fixed. Frontpage is browser cacheable and there is

no additional redirect anymore.

Spam controls are tightened further. Now all URLs (domains)

in database are daily rechecked.
