IRS Online Application for EIN (Form SS-4) Issues

For some time now (both before and after the shutdown), I have had technical difficulties getting an EIN issued online.  Roughly nine times out of ten I will get the message "Apply for an Employer Identification Number (EIN) online is currently unavailable
We apologize for any inconvenience this may cause. Please refresh your browser or try again later."  The most frustrating part is that you have to complete the entire application process before getting this message.

The few times a number was issued, it just seemed random.  I have tried deleting cookies, using different browsers, and applying at different times of the day.

Are any of you having similar difficulties?  Do you have other suggestions or insights that could help?

My thanks in advance for any ideas.
