Dear Sir or Madam,

The scheduled maintenance has been successfully completed.

The relocation of our SIM hosting infrastructure to the new data center was carried out as planned and without any issues. All affected SIM cards and services are fully operational again.

No further action is required on your part. If you experience any unexpected issues, please contact our support team.

Thank you for your patience and understanding.

Kind regards,

Your seven.io Team

Maintenance has started.

Dear Sir or Madam,

On June 18, 2026, we will be relocating our SIM hosting infrastructure to a new data center. This move will enhance service reliability and lay the foundation for the further expansion of our platform.

Maintenance Period
June 18, 2026, from 11:00 AM to 1:00 PM

Affected SIM Cards
This affects SIM cards currently operating on our existing hosting infrastructure. Not all customers or SIM cards are affected by this measure.

Impact
The affected SIM cards will be temporarily unavailable during the maintenance period. No connections can be established via the affected SIM cards during this time.

Once the migration is complete, the SIM cards will automatically be brought back online. In most cases, no action is required on your part.

Should you continue to experience service disruptions after the maintenance window has ended, please contact our support team.

Thank you for your understanding.

Kind regards,

Your seven.io Team

Maintenance has been completed successfully. All web services, including the dashboard, documentation, knowledge base, MCP server, and voice tester tool, are fully operational again. Message delivery remained unaffected throughout the entire window. Thank you for your patience.

Maintenance has started.

Following up on this week's maintenance, an additional maintenance window is required tonight between 01:00 and 02:00 CEST to complete the remaining work. Some of our web-based services may be unavailable for a few minutes during this window, specifically the dashboard (app.seven.io), the documentation and knowledge base, the MCP server, and the voice tester tool.

Message delivery itself is fully unaffected: SMS sending, voice calls, and all API endpoints (HTTP API, SMPP, inbound processing) remain operational at all times. There is nothing you need to do, and no messages will be delayed or lost.

The actual downtime will most likely be far shorter than the maintenance window itself. If anything seems off once the maintenance is complete, our support team is happy to help.

The maintenance appointment concludes without incident.

Maintenance has started.

We will be performing scheduled maintenance tonight between 01:00 and 02:00 CEST. During this window, a brief interruption of a few minutes may occur for the following services: dashboard (app.seven.io), documentation, knowledge base, MCP server, and the voice tester tool.

Core messaging operations are not affected. SMS sending and delivery, voice calls, and all API endpoints (HTTP API, SMPP, inbound processing) will continue to operate without interruption throughout the maintenance window. No action is required on your part, and no messages will be delayed or lost.

We expect the actual interruption to be significantly shorter than the announced window. Should you experience any issues after the maintenance has been completed, please don't hesitate to reach out to our support team.

What happened

A failure in one of our network switches disrupted the routing of inbound SMS traffic for a subset of numbers on our platform. As a result, some inbound messages were delayed or could not be delivered during the incident window.

Outbound SMS and all other services remained fully operational throughout the incident.

We are continuing to review the incident internally and evaluating additional safeguards to reduce the likelihood and impact of similar failures in the future.

We understand the importance and reliability requirements of inbound messaging and sincerely apologize for the disruption and inconvenience this incident may have caused.

If you have any questions or continue to experience issues, please contact our support team.

Thank you for your patience and continued trust.

After identifying the faulty network component, our engineering team restored the affected routing path and verified normal inbound SMS processing across the platform. Service has since been fully restored.

A failure in one of our network switches is disrupting the routing of inbound SMS to a subset of phone numbers. Our team is working to restore the affected component and bring inbound SMS back to full service. We will post another update as soon as the issue is resolved.

We are currently experiencing a partial outage affecting inbound SMS to a subset of phone numbers. Messages sent to the affected numbers may be delayed or fail to be delivered. Outbound SMS and all other services remain fully operational.

Our team has identified the cause and is actively working to restore full service. We will post updates as soon as more information is available.

We apologize for the inconvenience and appreciate your patience.

What happened:
Our monitoring system detected elevated error rates in voice message delivery and consequently automatically reported an outage. In reality, the voice platform remained available at all times.

Background:
The issue was triggered by an unusual delivery pattern from a single customer, whose high error rate temporarily skewed the aggregated success metrics that our monitoring system evaluates. For all other customers, the voice service was not affected at any time.

What we’re improving:
We’re looking into how we can more clearly distinguish anomalies in individual accounts from platform-wide issues in the future, so that our status reports more accurately reflect the actual service experience.

On February 1, 2026, between 7:58 and 14:30, there was a temporary disruption affecting SMS delivery. During this period, only a limited number of SMS messages were successfully sent. We apologize for any inconvenience caused. The service is now fully restored.

We would like to inform you about a temporary service disruption affecting our Voice Gateway. Between 12:58 CET and 13:03 CET, the gateway was unable to process calls.

The root cause of this incident was identified as a temporary overload of the memory interface, which prevented normal call execution during this period.

We sincerely apologize for any inconvenience this may have caused and want to assure you that we have taken measures to prevent similar occurrences in the future.

Thank you for your understanding.

Due to a power supply disruption, a portion of the hosted SIMs was unavailable for one hour.
