If you were trying to browse Tatoeba but ended up here on the blog, this is not a mistake. Tatoeba is currently down and will remain unavailable for a few more days. We hope to have it back some time this weekend (21st-22nd Dec). Very sorry for the inconvenience!
UPDATE (23 Dec, 00:50 GMT+1)
We currently have a new server up and the necessary data was transferred to this new server. There shouldn't be much left to do to have Tatoeba back, but we cannot work 24/7 on this and we don't know if we may run into some more unexpected problems, so we cannot guarantee the website will be available on Monday. We will keep you up to date if it should take much longer than expected though. Sorry again for the inconvenience and thank you for the supportive comments!
UPDATE (25 Dec, 4:30 GMT+1)
So as expected we had some unexpected issues which delayed us from bringing Tatoeba back up. And as you know this is Christmas and New Year's time, which means we are busier than usual with families and friends. As much as I hate it, all I can say right now is that Tatoeba still won't be back today. We still wish you a Merry Christmas though :)
UPDATE (25 Dec 20:00 GMT+1)
Tatoeba is now back! I have changed the DNS only a few minutes ago so you will have to give it a bit of time before http://tatoeba.org will actually bring you to the website instead of the blog. You can however go to http://188.8.131.52 in the meantime.
