- 11. INEFFICIENT WEB SERVICE CALLS
- 12. LOCAL INFRASTRUCTURE Infrastructure = required system components, the absence of which causes system failure (e.g. firewall, filesystem services) Service = required system data, the absence of which causes system failure for those clients that don't have cached copies of the data (e.g. DNS records, email, authentication cookies) Azure Infrastructure Outages: 0 minutes 100.00% Azure Service Outages: 0 minutes 100.00% Azure app outages due to local failures 8 hours 48 minutes 99.90% Azure app degradation due to local degradation 2 days 18 hours 37 minutes 99.24% Total Azure app downtime due to local issues 3 days 3 hours 35 minutes 99.14% January 2013-December 2013 uptime
