For the past couple days, Google Webmaster Tools has been having issues displaying the detailed links for a particular page of a site.
Many people are seeing what I am seeing:
When you try to download all external links or when you try to view external links for a specific page, an error message has been popping up.
when i try to check my internal or external links in webmaster tools by clicking on the hyperlinked number on the righthand side of the page, it gives me "Our system is currently busy. Please try again in a few minutes." for the last 2 days. This is true whether i use a different computer, different browser and for all websites i have listed there.
