  1. identified Dec 24, 2025, 10:40 AM UTC

    We are currently operating with reduced media capacity in our Manchester availability zone following a suspected hardware failure. There is no impact to services and calls are completing normally. Engineers are working to restore the affected hardware and capacity will be returned to normal in due course. In the meantime, our network is designed so that any single availability zone can carry the entire network load if all others fail. This update is for transparency only and no customer action is required.

    The affected hardware in our Manchester availability zone has been restored and reintroduced to the media pool. We are monitoring performance closely before marking this incident as fully resolved.

  1. investigating Oct 03, 2025, 09:07 AM UTC

    AirWallex, who we use for global automated payment processing, have "temporarily" suspended our account for incoming payments. They haven't said why or for how long and gave us the courtesy of zero notice. Any payments sent this route will therefore be returned to senders and not applied to Simwood accounts. Please use our back-up Lloyds Bank account which is shown in the document linked from https://si.mw/jp2qgym or one of the alternative payment methods (card or stablecoin) described at: https://si.mw/ro4n9hd . We apologise for any inconvenience and will update this as soon as we know more about this as yet unjustified (and in our opinion totally undeserved and heavy-handed) action.

  2. monitoring Oct 06, 2025, 09:53 AM UTC

    New payment processing is now in place in all currencies and account details are being updated now. Customers may continue to send to the Lloyds account but payments will be manually processed; sending to the new bank details (with only the account number as reference) will resume automated top-ups on receipt. AirWallex have refused to provide any information and continue to reject incoming payments. We will therefore be terminating all AirWallex accounts across all businesses, regardless of what this transpires to be, and updating details in due course.

  3. resolved Oct 06, 2025, 11:06 AM UTC

    Bank details are updated on the document linked from https://si.mw/jp2qgym (our support portal). Please note this is on the simwood.com domain - we will never email you bank details. Alternative payment methods (card or stablecoin) are described at: https://si.mw/ro4n9hd We're sorry for any inconvenience caused by AirWallex's grossly unreasonable and still unjustified actions.

  1. investigating Jul 24, 2025, 03:16 PM UTC

    We’ve received several reports of calls failing to certain mobile numbers. Our systems are operating normally, and we’ve found no issues within the Simwood network. There are indications the issue may lie with another network, and we’re actively monitoring the situation while we investigate further.

  2. resolved Jul 24, 2025, 09:23 PM UTC

    Following the initial reports of issues calling certain mobile numbers, we’ve been monitoring closely and can confirm once again that there have been no faults or abnormalities on the Simwood network throughout the period. While some customers may still experience issues, these appear to relate to factors outside of our network. We encourage those affected to consult general media sources for the latest updates on wider network conditions. Thank you for your understanding.

  1. investigating Jun 20, 2025, 12:41 PM UTC

    Customers connecting to our services in Slough over Cogent transit may have seen instability over the last 15 minutes or so. We have temporarily shutdown sessions with Cogent to alleviate any issues. Those on-net or reaching us over peering sessions (which is the majority) and other ultimate transit providers, or reaching other availability zones over Cogent have been unaffected. We strongly encourage all customers to connect into us directly wherever possible.

  2. monitoring Jun 20, 2025, 01:22 PM UTC

    Cogent have confirmed issues on their network. Our sessions with them remain shut down to prevent impact. We will continue monitoring and will only reintroduce routes for Cogent in Slough once we are confident their network is stable.

London: Reduced fibre network redundancy

  1. investigating May 29, 2025, 10:10 AM UTC

    We are seeing one of our physical fibre spans between Telehouse North and IXN hard down currently, suggesting physical disturbance. We have preemptively shut down links using this whilst it is investigated and repaired. This reduces redundancy around our London ring but as we have multiple other paths, no service impact is expected.

  2. resolved May 29, 2025, 12:15 PM UTC

    The span has been restored and the links have been brought back into service, restoring full redundancy around our London ring.
