Octotel will be performing emergency maintenance.

Date and Time: Tuesday, 7th April 2020, 16:00pm - 16:30pm
Affected Area

Duration

Upgrade description: Hardware upgrades.
Customer Impact: Residents will have intermittent connectivity during this
I can confirm this happened.

Would have been nice if someone let me know BEFORE it happened... like perhaps my ISP.
Does Octotel post their planned maintenance events somewhere for us mere mortals to check?

Unfortunately it doesn't seem like it resolved the underlying problem.

Perhaps this is part of a larger network upgrade?

Loss on my line is pretty much as bad as usual

Counts as essential service, so shouldn't have delayed upgrades.
Yes it does, but there are other partners involved in upgrading of backhaul links. A distributor being closed or running out of stock of the required SFP modules could cause a delay. Not saying this happened, but there could be parts of the supply chain which aren't considered essential.
