Internal server error accessing 'Updates' in OS X App Store

Question

Hi,
I just tried to access the App Store/Updates to update to 10.10.3, etc. and I get 'Internal Server Error - Read' with a few additional lines of text.  Is the server just overloaded?
Regards, Patrick

Triple-click the word "telnet" in the line below on this page to select the whole line:
telnet swscan.apple.com 443
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
You should almost instantly get three lines of output below what you entered, the last of which is this:
Escape character is '^]'.
If there's no output within ten seconds, consider that a failure. Otherwise, please post the output in a reply. You can then quit Terminal.
