Frankfurt Datacenter RCA: DE2000 Server (one shared/reseller hosting server in Frankfurt, Germany)

This is an RCA (root cause analysis) to the DE2000 server (one shared/reseller hosting server in Germany). This matter was already fully resolved earlier today, this message serves as a RCA follow-up. The issue investigated is primarily related to the accumulation of temporary files in the /tmp directory. This situation affected the performance and availability of websites that frequently interact with MySQL databases.

Despite the server remaining operational throughout the incident, there was indeed intermittent connectivity issues experienced earlier today for database-interactive websites hosted on DE2000. The primary effect of the excessive temporary files was on websites that heavily rely on database interactions. The built-up temporary files saturated the /tmp directory, thereby causing erratic website performance, marked by periods of intermittent availability.

We have successfully implemented a range of proactive measures and safeguards designed to prevent such situations from arising in the future. These strategies are not solely specific to the DE2000 server, but have been implemented across our entire shared hosting platform to avoid such a situation from occurring again in the future. Our Engineering team is also exploring additional improvements to our alert systems to detect and address such issues before they become a problem.

In conclusion, the recent incident earlier today involving the DE2000 server was caused by an accumulation of temporary files in the /tmp directory. While the server itself did not experience any downtime, it caused intermittent connectivity issues for websites that frequently interact with databases. However, we have taken corrective and preventive actions to ensure such scenarios do not recur across our shared hosting platform.
