Critical infrastructure such as healthcare and government entities were also impacted, including Universities such as Texas A&M University which had to cancel classes today due to this outage.
• The Importance of IT Support: Having a reliable IT firm with on-demand experts can significantly reduce downtime during technology outages and situations such as this.
