Storingsdossier · Ziggo Zakelijk · kabelaansluiting

Internet valt herhaaldelijk weg sinds 11 september 2026

Alle metingen op één plek voor de technische dienst van Ziggo. De storing zit volgens de metingen in het upstream-/retourpad of aan de CMTS-kant: het eigen netwerk is schoon, het downstream-signaal is goed, en het modem logt rond de storingen DBC-REQ-weigeringen, T3/T4-time-outs en Dynamic Range Window-overtredingen.

T3-time-outs

T4-time-out + Partial Service (28-09)

Kern voor de technicus

DBC-REQ denied → modem herinitialiseert binnen seconden. 26-09 02:28:24 en 06:52:51 (reject-other), 27-09 09:18:16 (code 204, reject-message-syntax, gevolgd door 5× Dynamic Range Window violation) en 27-09 22:07:08 (reject-other, na Unicast Maintenance Ranging – No Response). Elke keer volgt 2–4 minuten uitval, zonder dat iemand aan de apparatuur zit. Ook 25-09 10:03 en 28-09 12:43 een reject-authentication-failure (code 11).
28-09 15:50:43 T4 time-out (critical) + “TCS Partial Service”. Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received. Het modem kreeg geen unicast-onderhoudskansen van de CMTS en draaide daarna op een deel van de upstream-kanalen.
Korte storingen komen met een vast ritme van 18 min 39 s. De Ziggo-gateway (62.194.18.1) is 5–10 s onbereikbaar terwijl het modem gewoon antwoordt. Het ritme begint opnieuw na elke herregistratie van het modem, dus het hangt aan de sessie tussen modem en CMTS, niet aan de klok of aan iets in huis. Zie de grafiek.
Downstream is schoon, upstream-niveau normaal. SC-QAM 4–7 dBmV, SNR 37–40 dB, 0 ongecorrigeerde codewoorden; upstream ATDMA 39,8–40 dBmV. Toch terugkerende T3-time-outs en RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Top of the DRW — het retourpad of de CMTS-planning, niet het signaalniveau in huis.
Het eigen netwerk is uitgesloten. 0,00% pakketverlies naar de router, modem vrijwel altijd bereikbaar, verlies begint pas vanaf de Ziggo-gateway. Coax (gegoten kabel) gecontroleerd, modem en router herstart op 25-09 — de storingen gingen door.

Verzoek: onderzoek van het retourpad en de CMTS-kant voor deze aansluiting (DBC-REQ-weigeringen, T3/T4, het ritme van 18m39s) en zo nodig een monteur. De ruwe meetdata is beschikbaar.

Tijdlijn van alle storingen

Elke stip is één storing, op tijdstip en duur (logaritmische schaal). De kleur geeft aan op welke laag de verbinding brak.

Dagen met een modem-herinitialisatie springen eruit.

Het ritme van 18 min 39 s

De tijd tussen twee opeenvolgende korte storingen, per minuut. Bij toeval zou dat over de hele as verspreid liggen. In plaats daarvan pieken de tussentijden op 18,6 min en veelvouden daarvan (37,3 · 56 · 74,6 · 93,3 min): 40 van de 43 tussentijden liggen binnen 1 minuut van zo’n veelvoud, 22 keer precies één cyclus. Tussentijden rond een herinitialisatie van het modem tellen niet mee, want daarna begint het ritme opnieuw.

Pakketverlies en vertraging

Per kwartier, gemeten elke 5 s. Het eigen netwerk (router) blijft op 0%; het verlies begint pas bij de Ziggo-gateway.

Ziggo-gateway 62.194.18.1Eigen router 10.45.0.1

Hoogste gemiddelde vertraging per kwartier naar de Ziggo-gateway

Normaal ~12 ms. Pieken tot ~300 ms zijn merkbaar bij bellen en video, ook zonder volledige uitval.

Historie vanaf het begin (router-log)

Uit de UniFi-router, die sinds 02-08 logt. Tot 09-09 geen uitval; het eerste pakketverlies is van 09-09 23:11 en de eerste WAN-uitval van 11-09 21:54 (35 minuten). Vanaf 25-09 12:49 meet de monitor hierboven fijnmaziger.

Wat al is uitgesloten en gedaan

Coaxkabel modem → wandcontactdoos is een gegoten kabel en is gecontroleerd.
Modem en router herstart op 25-09 ~12:28. Daarna 32 SC-QAM + 2 OFDM-kanalen (daarvoor 24); storingen gingen door.
WAN-poort van de router: 0 fouten. LAN-verlies 0,00%, DNS 0 fouten.
Storingen begonnen 11-09, vóór de firmware-update van de router (12-09).
Bij de korte storingen blijft het modem bereikbaar; alleen de Ziggo-gateway valt weg.

Contact met Ziggo

26-09-2026 — Klantenservice gebeld. De eerste lijn kan het modem in bridge-modus niet uitlezen; technische dienst belt terug.

29-09-2026 — Terugbelafspraak technische dienst, 11:00–12:00.

Meetopstelling

Een server in het eigen netwerk pingt elke 5 seconden zes punten langs het pad naar internet. Breekt de verbinding, dan legt hij vast op welke laag, maakt een traceroute en leest het modem uit (eventlog elke minuut, signaal elke 5 minuten). Een storing telt als het internet volledig weg is.
