Ethiopia (E21) project completion/acceptance documentation was routed through an intermediary named 长城网际 ('Great Wall Cyber' or similar transliteration), which then delivered it onward to an entity referred to only as '进出口' -- plausibly a state export-import financing bank given the Belt-and-Road financing pattern gfw.report and others have already reported for this customer, but this ticket alone doesn't establish that identification with certainty.

Ethiopia (E21) customer specifically tested Melon VPN and Ultrasurf against TSG; Ultrasurf's frequently-rotating IPs required an updated signature (successfully blocked after update), while Melon VPN's connection succeeded but was non-functional for other reasons (not attributed to TSG blocking).

Confirms the full licensed TSG component roster deployed at Ethiopia (E21): Firewall, Digital Observer, Email Retention, Statistics Policy, Proxy, Session Record, GTP Security, AppSketch, AppSketch Engine, AppSketch DB, WebSketch, WebSketch DB. Several license terms were extended to expire 2091-12-31, indicating a multi-decade commercial commitment.

A field-operations runbook, "子卡槽位更换操作流程" (card-slot swap procedure), documents live maintenance work at the "Shashamane-IGW" site — one of the Ethiopian international-gateway sites named in the E21 site-codename mapping — upgrading an 8x10G link to 1x100G on device "9000-SMBIO-P01R01-1", including commands to force optical channels to bypass mode, physically relocate an optical port card, and switch the link back from bypass to inline mode, confirming the deployment operates in a passive/bypass-capable inline architecture.

Side-by-side internal performance comparison across Xinjiang (China Mobile carrier deployment, hostname cmcc-xj-server1-sapp-244), Fujian (domestic), and Ethiopia (E21) explicitly references the same 'app_sketch_maat' diagnostic log format at all three sites, confirming the identical AppSketch app-fingerprinting stack is used for domestic Xinjiang surveillance and for the exported Ethiopia deployment.

Direct dated evidence (July 2023) that the Ethiopia (E21) customer actively toggles application-level blocking as a live policy lever: lifting the block on YouTube plus four other apps caused a documented traffic surge and device alerts at the BOL-IGW site.

The 'E21' site code in Geedge's internal Jira maps to an Ethiopia deployment sold/serviced through CEIEC (中国电子进出口, a Chinese state-owned defense electronics company) as an intermediary — Geedge explicitly white-labels delivery documentation with an OEM template before it reaches CEIEC, and CEIEC's Ethiopia office director is named as directly relaying the customer's blocking requirements.
