On November 1, iGoogle will be retired. The BirdTrax gadget is hosted on an iGoogle directory, so it may no longer be available from the current URL. But no worries, BirdTrax is now hosted on Google Code, so here's what you need to do:
Update your gadget embed code. It should look something like this:
If you make this simple replacement, your gadget will perform equally well (and perhaps load even faster) than before.
BirdTrax is now hosted on Google Code, a reliable and fast server which is capable of managing the steady stream of code requests from the thousands of websites which use BirdTrax.
If you are unsure how to do this, you can use the BirdTrax Website Embedder Code Generator (the output has been updated). Using the code from this tool will do the same thing as is described above, and will keep your gadget working after November 1.
I apologize for this inconvenience. Please let me know if you have any issues!
