From 4:15pm to 4:40pm PDT on August 4th, a telephony partner experienced a disruption that caused connection issues for 2G/3G Particle devices. These devices were unable to connect to the Particle Cloud during this period.After the telephony disruption ended at 4:40pm PDT, some devices were stuck in a connection loop trying to connect due to an overloaded backend service in the Particle Cloud. Also, there were devices that did not achieve a stable connection and reconnected frequently, further increasing the load. Engineers deployed a fix at 5:23pm to reduce load on the backend system. By 5:41pm, the issue fully resolved: new device connections were successful and stable.Particle Engineers are validating a change to the backend system to reduce load in scenarios like this. It will deploy in the coming days without any customer disruption. We will continue to monitor and reduce load on this backend system in order to minimize disruption of the Particle Cloud.
