On the Helium network, a Consensus Group consists of 43 validator nodes randomly chosen in fixed intervals to provide network consensus.<\/p>\n<p>In the <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/engineering.helium.com\/2022\/07\/11\/network-disurption-post-mortem.html\">postmortem<\/a> for the event, Helium engineers cited two reasons validators stopped creating consensus on the network. <\/p>\n<p>First, an issue with a July 8 software update for validators contributed to the problem. The v1.12.3 update was designed to provide support for the 5G Mobile subnetwork and its MOBILE token.<\/p>\n<p>Additionally, a \u201clocal network outage\u201d was also to blame. In the project\u2019s Discord channel, Helium moderator \u201cDigerati\u201d explained that a high concentration of validators randomly chosen as the Consensus Group at the time of the outage was running on the same Amazon Web Service (AWS) network, which experienced technical difficulties.<\/p>\n<p>AWS is a global cloud computing and data storage service that can be used to enhance computer networks like Helium.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/s3.cointelegraph.com\/uploads\/2022-07\/70796087-fb54-47e4-91e4-779165d34ce5.PNG\"><figcaption style=\"text-align: center;\">A Helium community moderator explains an AWS outage affected validators.<\/figcaption><\/figure>\n<p>Compounding the problem was the failure of an auto-skip feature that should have chosen a new Consensus Group automatically.
