IT Business Continuity: The Leading Causes of Email Outages
Overview:
Email is a cornerstone of business communication, connecting management, employees, prospects, customers, vendors, suppliers, partners, investors, and analysts. Despite significant investments in technologies like replication, mirroring, and backup systems, email failures persist, largely due to technological issues.
Email Usage Trends:
Every day, the average email user sends 34 emails and receives 99, with overall usage growing at a rate of 53% annually. Even with robust infrastructure, email systems face frequent disruptions.
Research Insights:
MessageOne, a top provider of email continuity solutions, conducted research on the frequency and causes of email outages among North American companies using Microsoft Exchange or Lotus Notes. The study found that enterprise email systems are vulnerable to several types of failures, including:
- SAN (Storage Area Network) failures
- Misconfigurations
- Network access losses
- Database corruption
- Viruses
The survey indicated a 75% likelihood of unplanned outages and a 14% likelihood of planned outages annually.
Survey Findings:
A survey of MessageOne’s customers?"over 1,000,000 email users?"revealed the following about email outages:
- Frequency & Duration:
- 75% chance of unplanned outages
- 14% chance of planned outages
- Outage duration ranged from 2 minutes to 120 hours, averaging 32.1 hours
- Outage Duration Breakdown:
- 29% lasted between 4 to 24 hours
- 28% lasted between 1 to 4 hours
- 26% lasted more than 48 hours
- 17% lasted between 24 and 48 hours
Causes of Unplanned Outages:
Most outages stemmed from unforeseen technological failures:
- Server hardware failures: Accounted for 35%, averaging 18.1 hours
- Connectivity losses: Accounted for 19%, averaging 27.4 hours
- SAN failures: Accounted for 16%, averaging 25.5 hours
- Database corruption: Accounted for 16%, averaging 9.0 hours
Database corruption and SAN failures are particularly concerning because they are hard to prevent and often propagate issues to secondary systems. Resolving these issues typically involves reverting to tape backups to find uncorrupted data.
Impact of Natural Disasters:
Although natural disasters accounted for only 14% of unplanned outages, they resulted in significant downtime, with an average duration of over 60 hours, highlighting their substantial impact on businesses.
Conclusion:
Despite substantial investments, email systems are not immune to failures. As email becomes increasingly critical, businesses must include robust continuity plans that address the limitations of current backup technologies. By deploying more effective solutions, companies can minimize downtime and ensure reliable email operations.
