Issues on EIS Status

Ordinary Maintenance: DSS Cluster Maintenance

Mon, 08 Jun 2026 23:00:00 +0200

We will be conducting routine maintenance on the DSS Cluster. We anticipate minimal impact to services.

The active node will be temporarily brought offline for updates, and traffic will seamlessly route to the failover node.

Scheduled Maintenance

SIP Traffic Routing to Secondary Node

Maintenance Window

Start: Thursday, April 2 at 21:30
End: Friday, April 3 at 02:30 AM

Overview

During this scheduled maintenance window, we will be shifting our SIP traffic to our secondary node, which operates on the IP address 194.76.135.16.

Action Required

To prevent any disruption to your service, please verify your firewall configurations. As outlined in our Wiki documentation, the following subnet must be added to your allowed network list (whitelist):

Required Subnet: 194.76.135.0/24

Expected Impact

No Impact: Customers using the Webex Calling service, as well as customers who have already whitelisted the 194.76.135.0/24 subnet, will not experience any service disruption.
Service Interruption: Customers who have not whitelisted the required subnet prior to the maintenance window will experience a drop in SIP connectivity once the traffic shift occurs.

[Resolved] Planned Maintenance to BNG

Wed, 25 Mar 2026 23:00:00 +0100

We will be performing planned updates on our two Broadband Network Gateway (BNG) routers to ensure continued network stability and performance.

Expected Impact

To prevent downtime, these updates will be performed sequentially—meaning we will only update one router at a time. Because of this redundancy, the overall impact on service will be minimal.

Brief Reconnection: If your equipment is actively connected to the router being updated, your session will briefly drop.
Automatic Failover: Your modem or router will automatically re-establish its PPPoE session with our secondary, active router.
No Action Needed: You do not need to make any configuration changes or manually intervene during this process.

Note: If you experience an extended loss of connectivity after the scheduled maintenance window has concluded, please try power-cycling your modem/router before contacting support.

Services Temporarily Unavailable: The following services hosted in DC1 will be unreachable for the duration of the maintenance:
- Wiki
- Partner Portal
- API
- Website
Services with Automatic Failover: The following services are designed to automatically failover to our Data Center 2 (DC2) and should continue operating without disruption for customers and partners:
- SIP Trunk
- Webex Calling

Action Required for Seamless Failover:

To ensure the automatic failover functions correctly for SIP Trunk and Webex Calling, we kindly request that you verify that all necessary DC2 IP addresses are included in your network whitelists. Please refer to our documentation for the complete list.

We apologize for any inconvenience this necessary maintenance may cause. Our team is available to clarify any doubts or answer any questions you may have.

Thank you for your understanding and cooperation.

Sincerely,

EIS NOC

[Resolved] DSS Reachability Issues

Mon, 17 Feb 2025 15:00:00 +0000

One of our transit providers had an outage that caused some reachability issues for a small portion of customers.
We immediately disconnected the affected transit provider and reachability went back to normal.

[Resolved] SIP Server Urgent Maintenance

Tonight we will perform an urgent maintenace on the SIP Server to fix internal call routing for EIS for Carrier customers and to increase the antiflood limits to accomodate higher traffic customers.

[Resolved] DSS Call Routing Errors

Wed, 08 Jan 2025 06:02:18 +0000

Call routing for all DSS services was broken this morning at 7:02 AM for SIP Trunks and Webex Calling.

We have since identified the issue and have deployed a fix.

As of 9:05 AM calls are being correctly routed but we are keeping the services monitored.

Post Mortem

Service	Impact
DSS	MAJOR

Affected Products:

Product	Impact
SIP Trunk	MAJOR
Webex Calling	PARTIAL

Start Date of Incident:

08/01/2025 07:02 CET

Resolution Date of Incident:

08/01/2025 09:05 CET

Summary of Incident:

Calls were not being correctly routed by the platform causing errors for both inbound and outbound calls.

The cause was a bug in a specific software version of the RTP Server that caused an OOM error.

Mitigation Steps:

Restarted the affected services

Resolution Steps:

Update the RTP Server to permanently fix the issue

Action Items:

Improve our alerting system so that in the future we can take proactive action in similar cases
Change SIP Server responses to SIP OPTION so that in similar cases customer endpoints will be able to correctly fail-over to the secondary node
