CoSign Service Retirement on October 19, 2018

The CoSign service for Single sign-on (SSO) will be retired on Friday, October 19, 2018. Over the past several years, we have worked closely with schools and centers to migrate applications and services from CoSign to SAML, and are pleased to announce that the retirement is almost complete. 

In preparation, there will be a series of CoSign outages as we complete retirement maintenance and infrastructure updates. If you still have applications or services that rely on CoSign, please migrate them to SAML promptly, and be aware that there will be service impacts beginning next week.

Applications and services that have already migrated to SAML will not be impacted, and we will be logging all CoSign authentication attempts during this period. 

The scheduled outages are as follows:

  • Tuesday, October 9, 7:00 AM - 8:00 AM
  • Wednesday, October 10, 7:00 AM - 9:00 AM
  • Thursday, October 11, 7:00 AM - 10:00 AM

All applications and services that are still using CoSign will no longer be able to authenticate after October 19. If you need assistance, please contact the Penn WebLogin team at weblogin-tech@isc.upenn.edu.
