Preventative Maintenance Windows Schedule

OTech is committed to ensuring that all major components of its infrastructure are upgraded, patched and at recommended levels to meet our performance, reliability, availability and security objectives.

The scheduled PM windows allow OTech to increase our responsiveness to security threats, install timely upgrades to both server and networking hardware and software, and to implement critical infrastructure projects to proactively safeguard our customers. OTech coordinates all changes with the customers who will be impacted by work performed during these windows.

This maintenance schedule is listed by Day and by Resource. Please note that the Start and End times indicate the window within which maintenance will be performed; not necessarily the actual beginning and ending times.
