Outages & Service Degradations
Service Degradation - TLS Certificates for Secure Communications
Service Degradation – Sectigo Certificate Issuance Delays
We are currently experiencing delays in certificate issuance due to degraded performance at our certificate service provider (Sectigo).
What is the problem?
Certificate issuance requests are processing slower than normal because of an issue within Sectigo’s client and API infrastructure.
Who is affected?
Customers requesting new certificates, renewals, or reissues that rely on Sectigo services.
What services are impacted?
- Certificate issuance and related client portal/API operations
- Affected endpoints include Sectigo and partner client areas
Service Degradation - Multiple Services
Download speeds from Apple are currently very slow (2MB/s or lower) on campus or through VPN services. This is lengthening the amount of time it takes for an Apple macOS/iOS device update/upgrade to take place. Other large downloads from Apple may be affected. Device Management services from Apple do not seem to be affected at this time. ITS staff are looking into the issue.

Planned Maintenance - Data Center Operations & Services
The Top of Rack (TOR) network switches in the Lindquist Center (LC) Room 14 datacenter will be upgraded.
The Data Center Hosting team has identified devices lacking network redundancy at the TOR level. Those device systems/service owners have been contacted in a separate email, including a meeting invitation (and expectation) to attend the Infrastructure Day bridge event on Saturday morning.
For devices with TOR or alternate networking redundancy at the device level, there will be no interruption of service.
Planned Maintenance - Clickers
