Scheduled Maintenance
Manchester Infrastructure Apr 22, 20:00 - Apr 23, 03:00 UTC
On the night of Sunday 22nd we are relocating some of our infrastructure in one our of Manchester locations.

We operate a resilient fibre ring around our Manchester sites so our other locations should be unaffected but should be considered at risk during this window.

Directly connected customers will experience a short downtime while services are relocated.

Completed - Following last weekends maintenance, this has been postponed until a future date and will be announced via status.simwood.com as usual.

No planned maintenance is taking place this weekend.
Apr 14, 06:28 UTC
Scheduled - As part of our ongoing development of our platform we are undertaking further resilience testing on the changes deployed in recent maintenance.

This involves shutting down a production Redis database node and monitoring the recovery to ensure we can have confidence that, in the event of a real failure, automated recovery works as expected and services remain unaffected.

Again, this is very unlikely to affect production voice traffic but may impact statistics displayed in the portal or retrieved via the API, additionally there is a small chance that channel and rate limits will not work as expected during this time. In the event that our limiting experiences issues we operate on a 'fail safe' basis where our platform will disregard channel limits, ensuring calls complete, rather than limit calls based on out of date information about current use.

This has been tested multiple times in our development environment and as such we are confident that this will not be service affecting in any way but, as a precaution, services should be considered AT RISK during this maintenance window.

Completed - This maintenance was not completed as planned, and will be rescheduled for another date.
Apr 10, 08:45 UTC
Scheduled - We are introducing new inter-site links to add extra capacity and resilience between Slough and London as part of our normal capacity planning.

Whilst we anticipate no interruption to service during this, and routing of customer traffic will not be affected, it is prudent to consider these sites AT RISK during this time.

Completed - The DNS changes have been carried out without incident and the vast majority of DNS requests are now being served by Constellix (DNSmadeeasy) rather than Cloudflare. We will continue to monitor this closely, and any changes will be mirrored on Cloudflare for the next 14 days to ensure that there is no unexpected inconsistency.

The planned changes to Redis had a small negative impact on performance and, as such, we have reverted these and will review and reschedule as appropriate.

None of the above works were service affecting in any way, and the AT RISK period can be considered closed.
Apr 7, 08:38 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Apr 7, 07:01 UTC
Scheduled - Please note that we are undertaking some changes to our Redis servers on Saturday 7th April, we do not anticipate this being service affecting as these should not affect live traffic, however services should be considered AT RISK for this brief window, and statistics may briefly be inaccurate.

Furthermore, we're taking this opportunity to move our DNS for the main simwood.com domain from Cloudflare back to our previous provider - DNS Made Easy, which continued to host our other domains and reverse DNS records after simwood.com moved to Cloudflare in 2016.

We concentrate on what we're good at, and therefore don't run our own DNS or Mail services - relying on trusted external providers to provide these services - however, the importance of DNS cannot be underestimated. We moved to Cloudflare to take advantage of additional security features such as "Web Applications Firewalls" which, unfortunately, never worked as expected, and additionally introduced SSL issues. We swiftly disabled these, leaving Cloudflare as nothing more than a DNS provider - something where DNS Made Easy consistently ranks higher in performance and in features.

Despite the change to Cloudflare, the DNS Made Easy zonefile has remained current with any changes and we're confident that moving the primary NS records to DNS Made Easy will not result in any interruption of service. Additionally, we will maintain the records at Cloudflare for a minimum of 14 days to ensure continuity of service even where the NS records have been cached.
