Restarting image service around 10:10 this morning

Hi — we need to restart the image service this morning. Hopefully, there will be no-to-minimal disruption as a result of this, but we thought we’d best let you know it was happening, in case any bad images were encountered.
We’ll keep you posted as to progress, here.
Cheers,
Doug.

Image cache will start rebuilding in the next 15 minutes

Hi — we’re just about to boost the size of the image cache, which means that it will start rebuilding in the next 15 minutes or so.
This means that images may become unresponsive for a short while, but should be fine in very short order.
Thanks for bearing with us whilst we perform this work,
Doug.

Image service issues around 18:10

Hi — it looks like the new image service cache went over, which means that the cache is rebuilding, now. We’ve boosted the number of backend image servers to help it do this, and hopefully images should be responding within the next 5-10 minutes.
Sorry about this, obviously we need to increase the size of the image cache server to even bigger than we did recently. That’s something I’ll get on to doing tomorrow, after the current cache server has rebuilt and handled the rest of tonight’s traffic.
I’m just getting notifications from our alert services that images are back online, so that means they should be starting to work again for everybody.
Again, sorry about that wobble — I hope nobody was too seriously inconvenienced by it.
Thanks,
Doug.

Upgrading the image service cache 14:10

Hi — we’re about to upgrade the image service cache, which means that images may not load for a couple of minutes whilst the heaviest caching takes place.
This should only affect things for that couple of minutes, though.
Once this work is done, we should hopefully have fixed any issues around the image service for the time being.
Thanks,
Doug.

Images outage around 14:50

Hi — our image cache server fell over at around ten to three, today.
We quickly rebuilt another, more powerful, one, and are monitoring that as it rebuilds the cache.
We’ll be keeping an eye on things, but that should have fixed the issue.
Sorry to anyone who was inconvenienced by that,
Doug.

Some background work on image servers in progress, today

Hi — we’re doing work on the image servers in the background, today. Hopefully any disruption to images will be kept to an absolute minimum, as we’ve bumped the number of servers running to cover things like cache rebuilds.

However, it is possible that you may see broken images on occasion, and if you do, that’ll be the reason why.

Sorry for any inconvenience that may be caused, and thanks for bearing with us whilst we do this important work.

Image cache restart, 7:00 am today

Hi — we’ll be restarting the image cache in about 5 minutes.

This is to allow some updates to the image service to be deployed, as well as to allow for an increase in the cache size.

We’re provisioning lots of extra image servers to cover the rebuild, so hopefully people shouldn’t notice anything being slow after the first minute or so.

Thanks,

   Doug.

Image cache rebuilding

Hi — we’ve restarted the image servers, and the cache is rebuilding.

Sorry about the disappearance, there.

This shouldn’t affect the rest of the work planned for this evening.

Thanks,

   Doug.
