If you visit this site regularly (which is recommended because of the frequent updates that we have) you will have noticed that the Street View embeds stopped working some days ago. Instead of showing the interactive streetview, we saw a blurry, pixelated mess that would not load further. Here is a screenshot of the problem.

The problem lies with Google. All Streetview embeds stopped working. There is a support thread about this streetview problem here:

For now, all Streetviews on this site have been disabled and screenshots are shown instead.
You can still go to the Street View by clicking the green arrow at the top right (see screenshot).
I hope Google fixes the problem, soon. We are not the only site affected by this error. I will keep you updated should there be any news.
UPDATE 1:
There is another support thread here:

UPDATE 2:
Google is now working on it.
Hi everyone,
Thanks for reporting this error. The Street View folks are looking into this right now, and I’ll make sure that somebody posts an update here when we have more information available.
Appreciate your patience!
UPDATE 3 (Oct/07/2010)
A Google employee just announced that the problem was located and that a team is working on a bugfix. The employee said that the issue should be resolved by the end of the week.
