• No PSTN customers out of service. Severe congestion due to low capacity. 999 services restored.
• Re-routes – 52 – re-routes suspended due to systems failure (escalated resolution)
• GS – BSkyB fault due to another fibre issue ETR 14:00. 363 faults reported, 17 confirmed restored, although expect more to clear as customers arrive this morning
• BTW – 456 faults ( down from 506). 238 cell sites still affected ( down from 283 )

• All Met Police ccts to all three sites have been restored.
• All urgent Airwave ccts have been restored.
• Government circuits have been restored.
Action Plan and Progress
• High level Plan (cables are numbered in order of priority)
• Action 1 - Identify damaged cables and ccts and establish priority plan – complete (fluid)
• Plan A – Stage 1 Openreach to provide new street level cables
· Provide 3 x new 276 fibres at street level. Complete.
· Provide 4 x new 276 fibre cables at street level. Not yet pulled in.
· Priority cable 1 complete and working
· Priority cable 2 complete and working
· Priority cable 3 ETA 17:00 today
· Priority cable 4 ETA 19:00 today
· Priority cable 5 ETA – being reassessed
· Priority cable 6, 7 and 8 – no ETA
· If all target completion times are met today, 30% of the damage will be restored.
• Plan B – Re-route using all existing spare fibres.
• This is nearly complete but we are still finding new fibres and using them to re-route services as they become available.
• Plan C – Provide and utilize PDH and SDH radio systems if required
• PDH unit on site. SDH unit may not be available, checking options – no ETA
• Plan D – Provide Sat Comms solution if required
• Establishing the viability and suitability of this option. Unlikely to be viable
• Plan E – Restore damaged copper cables (thought to be only 1 live) – no ETA
• Plan F – Repair tunnel and cabling – no ETA
NB Plans A and B are active and running in parallel. Indicative target time for all damaged cables to be off-loaded – late 9th April (this is not a commitment, only a target)
Other Key Issues and Updates at 07:50
• Cumulative number of fibres repaired – 192 or 10.2% (up from 96 / 5.2%)
• Cumulative number of 2 Mb/s equivalent circuits restored – 6995 or 15.2% ( up from 1883 / 6% )
• In total there are 1,836 fibres are to be repaired. If we have no further delays, we expect to have 30% of ccts recovered by CoP today. Current expectation is that the repairs will run through to Thursday.
