Some clients are reporting issues with CONGESTION on their phone systems. This is a symptom of additional load on lines linking all carriers as a result of staff being sent home to work.

While this incident is extraordinary due to Covid-19, XSTRA is working around these issues as best as possible. Please do not call us on issues of congestion for both inbound and outbound calls.

We will be providing updates here directly from some of our carrier partners as we receive the information.

Thank you for your patience at this time.

UPDATE 16: 25/03/2020 11:45AM AEDT

Update on Interconnect Capacity links experiencing congestion since COB yesterday.
Symbio Networks can confirm Inbound traffic has increased by over 80% and forecasting to reach double by the end of the week.
Telstra, Adelaide CCA
Symbio Networks will increase by a total of 57 E1’s for the Adelaide CCA.
Phase One – Symbio have ordered 14x E1’s today. The pre patching and tie cables are ready for this expansion. This has a target implementation date of the end of next week.
Phase Two – Symbio will increase capacity with a further 43 E1’s in this CCA. More information and ETA will be provided on this ASAP.
Further Expansions
Symbio Networks have increased the Optus capacity overnight by a total of 300 channels (150 channels in NSW and 150 channels in QLD). This brings the total national increase to 2,000 channels with Optus since last Monday, 16/03
As per announcements from the other industry carriers, interconnect links between carriers are strained due to the rapid scale of these increases attributed to the COVID-19 coronavirus. We will continue to provide updates on capacity expansions. Unfortunately, we are unable to provide an ETR at this stage.
Next Update: 18:30 Wednesday, 25/03

HISTORICAL UPDATES ON THIS ISSUE

________________________________________

UPDATE 1 : 1:39PM AEDT 16/03/2020

Due to unprecedented call volumes, we are experiencing congestion on our carrier interconnect trunks. Our engineers are investigating. We’ll provide an update once more information becomes available.
________________________________________
________________________________________
UPDATE 2 : 3:13PM AEDT 16/03/2020

Inbound traffic update:

We’re working with our carrier interconnect partners to ensure traffic is being evenly distributed across all trunks and paths.
We are also working with these partners to increase capacity.

Outbound traffic update:

We have negotiated with several customers with high per-second traffic to divert calls away from us temporarily.

We have increased capacity on some outbound carrier trunks where no network upgrade was required, and and we have rerouted traffic within our network to optimise the utilisation of outbound capacity.

The situation should now be improved.
________________________________________
UPDATE 3: 08:35AM AEDT 17/03/2020

Congestion Mitigation:
As per earlier updates, Symbio has implemented a number of network grooming measures throughout the course of today (Monday). In addition, Symbio has identified and is in the process of implementing further actions to manage the observed surge in traffic. Combined, these actions will alleviate overall congestion during peak call volume periods (0830-1300 AEDT).

Earlier congestion issues eased towards the end of the business day as traffic volumes subsided. Whilst the measures already taken will alleviate congestion, Symbio will be closely monitoring overall network performance from the start of business tomorrow, Tuesday, to verify network capacity/utilization. Further status updates will provided by midday local AEDT.

Capacity Increases: In parallel, Symbio is actively working with our local carrier providers to expedite the delivery of additional Carrier Interconnect (CI) capacity across the network. As the new capacity becomes available it will be added to the network on priority. Symbio support and technology teams are aware of this major incident impacting our customers and will be closely monitoring tomorrow morning at peak times

UPDATE 4: 11:50AM AEDT 17/03/2020
Telcoinabox / Ivox apologizes for the lengthy impact and congestion on our network. Presently, resolving this incident is the number one priority to our business, with all teams and executive management working towards driving a resolution. Symbio networks are working closely with our carrier partners to alleviate the congestion on our network.
What has caused this sudden spike in traffic?
External factors showing unprecedented increase in inbound call logs. This can be attributed to the COVID-19 (or Coronavirus) pandemic being experienced around the globe.
Actions:
Symbio Networks have worked with Vodafone to expedite bringing into production new carrier interconnect capacity under a change request last night between 12-3am.
Yesterday afternoon, Symbio worked with Optus to increase our carrier interconnect capacity. We are continuing to increase this further today by distributing Optus traffic more evenly across our network. Evenly distributing this traffic is now a priority due to the sudden spike in traffic.
Symbio is also working with AAPT to increase call capacity. Executive management have escalated all orders to expedite this process.
Lastly, Symbio are working closely with Telstra to have their core routing updated to allow their traffic to be distributed evenly across the call collection areas. In parallel to this, Symbio networks are escalating all new capacity orders to accelerate the process.
====================================================
UPDATE 5: 17/03/2020 4:50
Dear customer,

Symbio Networks are continuing to work with our carrier partners to minimise congestion on our network. We apologies for the extended impact; please understand we are experiencing a high influx of traffic due to the COVID-19 virus.

This incident is our top priority.

This is a dynamic situation and we are constantly reviewing and, where possible, changing traffic patterns to alleviate the observed congestion.

________________________________________
UPDATE 6: 18/03/2020 1:45PM AEDT

Symbio Networks are continuing to work through the congestion issues being experienced on the carrier interconnect (CI) links between carriers for the past three days with the unprecedented traffic increases. Below is an update on how the industry is working together to alleviate the impact to our customers

Symbio Networks in conjunction with the other interconnect carriers have identified that one service is generating extreme traffic volumes in multiple call collection areas (CCA), resulting in the congestion. We have identified this as the Coronavirus Hotline, and we are working with the end user of this service and the other carriers involved in the call path to have traffic redistributed to CCA’s with spare capacity.

In Sydney and Melbourne, Symbio Networks are analysing calls to identify if there are any other specific high-volume numbers which are causing a significant impact. Targeting these high-volume numbers can allow us to free more capacity for other calls on our network in the short term.

In other measures we are continuing to work with the carrier interconnect partners to expand the capacity between both networks. Currently, Telstra and Symbio are expediting a change request (involving physical works within Telstra exchanges) to increase the capacity on these CI links. This change has many moving parts, but we have a targeted delivery date of the end of next week.

This incident has the full visibility of executive management and has Support and Technology teams working tirelessly to resolve this incident. Over the last 48 hours we have seen the industry come together to ensure voice services, which are still the primary means of communication, remain operational.

________________________________________
UPDATE 7: 19/03/2020 8:00AM AEDT
Here is an update on the ongoing major incident involving congestion issues being experienced on the carrier interconnect (CI) links between carriers.

Symbio Networks was able to further alleviate congestion in Newcastle and Hobart by rerouting the traffic of a high-volume customer to alternate paths within our Network. As a result, we have seen call congestion decrease in these areas.

Our Technology and Support teams continue to work with our Carrier partners to increase capacity for other parts of Australia, with main focus on our Melbourne and Sydney Infrastructure. Given the magnitude of these changes, and the number of parties involved, these works will take time to complete. We are working to reduce the lead times and will keep you updated as new capacity becomes available and is introduced into the network.

We aplogise for the lengthy delays but are working hard with our industry carrier partners to drive resolution.
________________________________________
________________________________________
UPDATE 8: 19/03/2020 12:10PM AEDT

After analysing the peak-time traffic patterns from today, we can confirm the congestion being experienced in Newcastle and Hobart has been relieved.

We are continuing to work with our carrier partners to alleviate the congestion in other major cities, with our main focuses being Sydney and Melbourne. As mentioned in our previous update, given the magnitude of these network changes, and the number of parties involved, these changes will take time to complete.

We apologise for the lengthy delays but are working hard with our industry carrier partners to drive resolution.
===========================================================
Update 9: 19/03/2020 COB

During a further day of substantial traffic increases we are continuing to work closely with our carrier partners to alleviate any areas of interconnection which is experiencing congestion. With recent changes we have alleviated 2 major regional Call Collection areas (Hobart & Newcastle).

There is also no congestion between Symbio and Optus, Vodafone, TPG/AAPT or Vocus.
At peak times today the congestion was isolated to links between Symbio and Telstra within Sydney and Melbourne. Telstra and Symbio have initiatives in place which are progressing well.

We have also kick-started initiatives with the other carriers to ensure headroom for any further potential spikes.
