Partial restoration pattern¶

The partial restoration pattern is the recurring shape of Internet-connectivity recovery following a government-directed shutdown: connectivity comes back in phases rather than at once, with the timing of each phase aligned to political or operational milestones rather than to a clean service-restoration curve.

Three recurring phases appear across the Cloudflare Radar corpus:

Hard blackout — near-zero traffic from the country, typically lasting hours to days.
Partial restoration — connectivity returns to a subset of users, networks, or services. Traffic rises from ~0 to some fraction of baseline. Timing often aligns with a political event (announced election result, ceasefire announcement, state TV statement).
Full restoration — the regulator or the operators publicly announce restoration; traffic returns to baseline over hours to days.

Canonical instance: Uganda 2026¶

Uganda's January 2026 pre-election shutdown shows each phase cleanly:

Hard blackout: January 13 at 18:00 local (15:00 UTC) through January 17 at 23:00 local (20:00 UTC).
Partial restoration: January 17 at 23:00 local — "Internet connectivity was partially restored after incumbent President Yoweri Museveni was declared winner of his seventh term." The restoration is explicitly coincident with the political milestone.
Full restoration announcement: January 26 — "Full Internet restoration was announced by the UCC on January 26." Mobile network operators MTN Uganda and Airtel Uganda both confirmed on social media.

The ~9-day gap between partial and full restoration is politically significant: it lets the regulator keep leverage over operators and users even after the electoral event is technically over.

Why this shape is predictable¶

Governments that order shutdowns typically:

Want the shutdown to coincide with a politically sensitive window, not to last indefinitely.
Want to signal control by restoring connectivity on their schedule rather than the operators' schedule.
Want to avoid collateral economic cost beyond what the political milestone requires, leading to a phased walk-back.

The result: phased restoration is not an engineering phenomenon (restoring connectivity is operationally near-atomic once the order is lifted), but a political-communication phenomenon — each phase communicates a message.

Other shapes¶

Not every shutdown ends with this phased pattern:

Iran's January 8 2026 shutdown partially restored for a few hours on January 21 and January 25 before each reversal, then more aggressively recovered starting January 27 — the restoration was non-monotone, reflecting state indecisiveness rather than a scheduled walk-back.
Iran's February 28 2026 shutdown began its first partial restoration on May 26 2026 — 87 days into the shutdown — one of the longest sustained Internet disruptions in recent years. The recovery shape was capital-localised (91.6% of restored HTTP requests originated from Tehran), defining a new shape variant where the "partial" in "partial restoration" refers to geography rather than to time along a phased recovery curve. Diurnal pattern returned within hours (decline ~21:00 UTC, return ~03:00 UTC 06:30 local Tehran), confirming organic user activity. Traffic peaked at only ~40% of 2026 maximum even at recovery onset. See concepts/capital-localized-internet-restoration for the geographic-shape canonicalisation.
Republic of Congo's March 2026 election shutdown had a ~60-hour hard blackout then recovered "rapidly returning to pre-shutdown levels" starting March 17 at 18:20 local — no extended intermediate plateau, just a clean return.

Multi-month shutdowns: the "missing-partial-restoration"¶

variant

Iran's February 28 2026 shutdown has elaborated the original three-phase shape with a fourth observed variant: the multi-month sustained shutdown that eventually partially restores asymmetrically by region. The Q1 2026 disruption review framed this as the "missing partial-restoration phase" (because two months in, no milestone-based recovery had occurred), but the May 26 2026 follow-up showed that when the partial-restoration phase finally arrives for a multi-month shutdown, it tends to come capital-first — a distinct shape from the time-based phased pattern that characterises shorter election or protest shutdowns. The Iran Feb 28 shutdown is therefore canonical for both:

Missing-partial-restoration over the short horizon (no recovery for 87 days; in late April the Q1 review classified this as the missing variant).
Capital-localised partial restoration when it arrives (May 26 2026; see concepts/capital-localized-internet-restoration).

Observational value¶

For external observers, the phased-restoration shape provides useful inferences:

Which phase the shutdown is in narrows the expected duration envelope (a country in the "partial restoration" phase is typically within a week of full restoration).
Non-monotone recovery (traffic up then back to zero) is a warning sign of state indecisiveness and potential prolonged shutdown.
Missing partial-restoration phase (no political milestone triggered an intermediate recovery) often correlates with filtering-based mechanisms that the state continues to benefit from keeping in place.

Seen in¶

sources/2026-04-28-cloudflare-q1-2026-internet-disruption-summary — canonical wiki instance. Uganda 2026 is the textbook three-phase shape (hard blackout → partial restoration after declared winner → full restoration announced 9 days later). Iran's January 8 shutdown shows the non-monotone variant (partial restoration on January 21 + 25 both reversed before aggressive recovery started January 27). Iran's February 28 shutdown shows the missing-partial-restoration variant (2+ months of sustained <1% traffic and no meaningful milestone-based recovery at quarter-end).
sources/2026-05-27-cloudflare-irans-internet-is-partially-restored-cloudflare-radar-data-shows — Iran February 28 follow-up: the missing-partial-restoration variant resolved into the capital-localised partial restoration variant on May 26 2026, 87 days into the shutdown. 91.6% of restored HTTP requests from Tehran; TCI / IranCell / RighTel / MCCI all rose simultaneously; diurnal pattern returned within hours. Peak traffic only ~40% of 2026 maximum. Cloudflare flagged the recovery as potentially temporary — January precedent had two reversed partial restorations before durable recovery.
