Moving S3 solution

    This incident has been resolved.

    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.

    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.
