Outage Events and Overall Uptime reflect events lasting 5 minutes or longer across 2 of EHF's 5 managed networks.

Summary: 3 outage events were recorded this period, with 116 minutes of downtime in total. Overall uptime across those networks was 99.87%, compared with 99.71% in September.

EH - Main House: 2 events totaling about 74 minutes (Oct 9 and Oct 18). On Oct 18, the primary internet circuit dropped and the network's security appliance became unreachable from the Meraki cloud for about 52 minutes; service returned once the provider restored the circuit.

EH - Lake House: 1 event totaling about 42 minutes (Oct 21). The security appliance, switch, and access points went offline together and returned together, consistent with a brief power interruption at the site.

Other alerts were also logged this period and are tracked separately from outage events: 5 client IP conflict detections at EH - Main House and 3 gateway to repeater changes across EH - Office and EH - Guest House. These are configuration and link-quality signals rather than outages and were not included in the uptime calculation. EH - Barn also logged 2 brief access point drops, each under 5 minutes, which fall below the outage threshold.

About this signature: the most frequent signature this period matches CVE-2021-44228 (Log4Shell), a remote code execution flaw in the widely used Apache Log4j logging library that is still scanned for at scale across the internet. Meraki's firewall blocked the matching inbound attempts before they reached any EHF device. Meraki retains threat/event data for a maximum of 15 days platform-wide, so this reflects the trailing 15 days at time of export, not a full-month count.
