Production Outage: February 5, 2018 4:46 pm - 5:53 pm PST
For more than a year TokBox has exceeded it's 99.95% availability targets. On February 5 we experienced a significant interruption to North American data centers that lasted a little more than an hour.
All connectivity to the platform was impacted in the North America Region because API servers could not resolve HTTP requests that are used for session negotiation.
API traffic routed to other data centers, such as London, worked as required
Our first internal alert was triggered at 4:48pm
At 5:05pm, our severity-one channel was alerted and all stakeholders were notified and immediately convened as the Production swat team assembled for analysis.
At 5:14pm the status page at status.tokbox.com was updated with corresponding findings after the triage based on internal tests.
At 5:50pm connectivity and service was restored.
We saw a sudden service degradation in HTTP API response latency.
Initially our production team noticed an apparent loss of connectivity between our top level HTTP API Servers and Redis (cache machines).
API servers started running out of file descriptors as a part of this loss of response.
We determined the cause for the failure was a 700% increase in traffic to our API service. This essentially resulted in a deadlock in the API servers where requests were not being serviced and additional new requests were piling up further exacerbating the problem.
We have approximately doubled our API server capacity in 3 major geographical regions - San Jose, New York and London to make sure an additional buffer exists.

Even though all traffic has resumed normal operations we are continuing to monitor and investigate the root cause.
