(Updated to include link to USPTO’s 411 page.)
It seems that all USPTO systems are broken.
Members of the EFS-Web listserv, the Patentcenter listserv, and the e-Trademarks listserv (each of which you should join if you have not done so already) are reporting that all USPTO systems are broken just now.
Here is the link to USPTO’s 411 page: https://www.uspto.gov/blog/system411/ . Right now it says:
USPTO is experiencing an enterprise wide issue. Users are reporting being unable to connect to the USPTO network and receiving the error “revocation status of the smartcard could not be determined”. Support groups are troubleshooting this situation, but other impacts include share drive mapping issues, SharePoint access issues, and other applications may have impacts as a result of this situation. Users are advised not to contact the Service Desk at this time. Due to the High Call Volume that the OCIO Service Desk is experiencing, there are reports of some users receiving busy signals when calling.
