Moving S3 solution
ResolvedMaintenance51 minutes
  • ResolvedUTC
    This incident has been resolved.
  • InvestigatingUTC

    We're changing our S3 provider due to ongoing issues with the current solution. This has some consequences for our clients.

    We will be moving to our secondary hosting provider, Leaseweb Amsterdam, who already hosts the server sending out emails. This means that it will not impact any existing or future Data Protection Agreements.

    Since we store copies of HTML and text content as well as attachments in S3 the move means that this data can not be accessed until we have moved all historic data from our old provider to Leaseweb. This will take some time - we do not know how long yet since our current provider is having performance issues.

    Thus, we have disabled the resend function in Heysender which makes it possible to resend an email to a recipient. Since we can not access the content of the email we can not resend it.

    We apologise for any inconveniene caused. Get in touch with support if you have any questions.

Issue with incoming connections to Heysender
ResolvedMajor outage61 hours 37 minutes
  • ResolvedUTC

    All systems are running as expected. We're marking this as fixed.

  • UpdateUTC

    We're sending emails without issues but we're still not logging HTML and text content or attachments. We have decided to let everything stabilise so on Monday we will bring everything back to working order.

  • UpdateUTC

    Our hosting provider is still working on bringing their S3 storage back up. We're sending emails without issues but we're still not logging all data due to S3 storage being offline. We will update here when we're actively logging everything again.

  • MonitoringUTC

    We're sending emails again. We have bypassed S3 storage which we use to save HTML content, text content and attachments of sent emails. For now these will not be saved to log and will not be available for lookup in the interface. As soon as S3 storage runs again we will re-enable it.

    We apologise sincerely for the issues this has caused. If you have any questions do not hestitate to contact support.

  • UpdateUTC

    S3 has been bypassed. We're running final tests before opening the system externally. We will update again within the next 20 minutes.

  • IdentifiedUTC

    We're working on bypassing S3 storage to get all systems running again. We will update again within the next 20 minutes.

  • InvestigatingUTC

    Due to an issue with our hosting provider's S3 storage we're currently experiencing difficulties accepting incoming SMTP and API connections. We're looking into solutions. New status will follow in 20 minutes.
