A recent AWS outage was caused by a DNS problem that hit the AWS DynamoDB endpoint, making it unavailable for services to access. The issue was fixed in about [--] hours, but then another issue arose with EC2, the system that creates virtual servers. This incident highlights the importance of having a robust disaster recovery plan and being prepared for such outages.

"Multi-region on AWS sounds great until you see the bill. Client was paying $3400/mo for a second region that handled 2% of traffic. Cross-region data transfer alone was $800.
