Server Maintenance and Facebook

On October 4, 2021, Facebook together with WhatsApp and Instagram haven't been accessible for 6 hours. Facebook is a social network where member share messages with online friends. It includes also a marketplace for small business.
Theoretical calculations come to a loss of 60 million US$.

What happened?

The information policy of Facebook wasn't very helpful. They claimed a wrong server configuration as reason.
External experts assumed that the outage was the result of DNS failure. DNS, in short for Domain Name System, is like a phone book for websites.

Anyway, the services haven't been available.

Server Maintenance is necessary

While Facebook has millions of active users, we are dealing with around 300 visitors per day on CLOUGLOBAL. So we are not heavily impacted in case of downtime.

During the Facebook outage, we had to suffer from two minutes. Sorry for that.
Our regular server maintenance is automized and is done twice a day.
It includes

  • Image and file backups to an autonomous server
  • redundant database updates
  • spam blocklist update and scan
  • check for unauthorized file changes
  • malware scan
  • vulnerability scan
  • editor audit
  • firewall update
  • server tools updates

Still, when the server is not reachable, it's not in our hands because we need to rely on an external service.
