My understanding is that the ad units are filled in the order they are rendered on the page. If there is insufficient ads available for the page (based on its keywords), the last ad unit may be empty. If you have a table layout this might explain why the large rectangle sometimes doesn't appear, but I have no ideas about why the wide skyscraper does not appear.

I suppose the rectangle could appear for an image ad, and if there are no ads for the skyscraper, then that appearing blank I use the 'alternate ad' feature from Google to remove the white space, so users get a slightly different view of the page in these circumstances.

Could be an ad inventory issue why not all ad units are showing ads. Or an inventory issue for your specific geotargeted location. Also, if you just added them to the page, it can sometimes take a day or two to display ads in second and third ad units.

If you have a table layout, I assume you have html something like this for your ad units: <tr>
<td>wide skyscraper</td>
<td>large rectangle</td>
<td>content</td>
</tr> In this case the wide skyscraper cell will load first and Google's script will link to Google to request ads. The large rectangle cell will load next and send another request to Google, but there may not be any ads left to display. With a div layout you can have more control and can make the large rectangle load first, although it stays on the same position on the screen. But this wouldn't necessarily solve your problem. One check you could do is to use the Google preview tool to see how many ads are available for your page in different countries. If there is only a few then you will never fill both ad units.
