Summary

  • AFRINIC’s 18 September 2026 invitation reports 257 deployment milestones from 19 Deployathons, with 246 participating organisations across 27 countries.
  • A 21 February 2023 AFRINIC blog reported 377 milestones from a programme that explicitly combined Deployathons and the DO Helpdesk, with 149 organisations across 32 countries.
  • The 120-count difference does not establish a decline. The sources use different dates and stated scopes, and publish no crosswalk, counting unit, deduplication rule or cohort-level record.

Two AFRINIC publications give readers two totals for the organisation’s IPv6 deployment support. The newer one is smaller. That is worth noticing, but subtraction is not an explanation.

The 18 September invitation for an October Deployathon in Gaborone says the programme has run 19 Deployathons. It reports 246 participating organisations in 27 countries and 257 deployment milestones. A blog post dated 21 February 2023 says 377 milestones had been achieved by 149 organisations in 32 countries. Its wording is explicit about scope: the figure covers the Deployathon and DO Helpdesk programmes, with the country figures dated to February 2023.

AFRINIC publication Stated scope Milestones Organisations Countries
21 February 2023 Deployathon and DO Helpdesk programmes 377 149 32
18 September 2026 19 Deployathons 257 246 27

The raw difference is 120. It cannot be described as 120 milestones lost, withdrawn or disproved. The 2023 figure combines two support channels; the 2026 notice names Deployathons and separately mentions more than 100 helpdesk calls, but does not say whether helpdesk-generated milestones remain inside its total. The later notice also does not state a measurement cut-off or explain whether old records were retained, reclassified or recalculated. A narrower scope could account for some or all of the difference. So could a change in definitions or reporting practice. The published material does not settle which.

“Milestone” covers unlike evidence

The categories are not all the same kind of event. In its 2023 annex, AFRINIC defines a valid route6 object as an IRR record. A validated address plan is recorded as implemented in an IP Address Manager. An advertised IPv6 prefix is visible in the Internet routing table. The annex describes test-VLAN traffic as traffic running in an organisation’s test environment; an IPv6-enabled customer, by contrast, means a final user can send and receive IPv6 traffic.

The 2026 notice likewise groups different stages: route6 and RPKI objects, address plans, advertised prefixes, an IPv6-enabled core, test-VLAN traffic, DNS and user traffic. Those are all potentially useful markers. They do not prove the same thing. A registry object records a configuration or administrative state; a user-traffic entry points to a later operating stage. Neither alone reports reliability, customer reach, duration or the share of an operator’s network involved.

The 2026 notice’s 11 displayed category counts add to 241, while its headline total is 257. The 2023 post prints five example category counts that add to 226, against 377 overall. Both lists are introduced as examples, not complete breakdowns. Neither source says whether one organisation or deployment can appear in several categories. The differences of 16 and 151 therefore cannot be called missing milestones.

Nor can three networks with IPv6 user traffic be divided by 246 organisations to produce an adoption rate. One number counts milestones of a particular category; the other counts participating organisations. The notice does not link a milestone to a distinct organisation, say how many organisations participated more than once, or define the population of African networks. Three is the reported value of one programme category, not the number of IPv6-capable networks in the region.

A comparison needs a bridge

The two snapshots are still useful. They show what AFRINIC has chosen to report at two points in time and expose the question the reader cannot answer: what precisely is included in the new total, and how does it relate to the older one?

A comparable series would state its cut-off date, programme channels, unit of count and rule for organisations that participate more than once. It would define each category and explain what evidence is required to mark a milestone. If a measure changes, a short crosswalk could show whether a channel was excluded, a category renamed, a record reclassified or a cohort recalculated. None of that requires publishing confidential customer configurations. It requires a stable description of what the published numbers mean.

The upcoming Gaborone event does not yet supply the missing comparison. The invitation schedules it for 6–9 October, after the application deadline of 22 September. On 28 September, the meeting has not happened and no attendee selection or outcome is established. The article therefore reports the notice’s cumulative claims, not results from that event.
