Hank here from Shopify.
Thank you for reaching out about this, and apologies for the inconvenience caused.
We are aware of a small number of stores being inaccessible the past few hours, and our developers have been working on this to resolve the issue.
The developers have confirmed that access has been restored to these stores, however, we are still seeing some slow loading times in the admin. This is still being worked on currently, and we are hoping to have an update shortly with regard to this.
I will share this link also, where you can check for any individual issues with your store itself.
Thank you for your understanding, and I will report back here once I can confirm the issue has been resolved.
All the best,
Hello again all.
Our developers have confirmed that this issue is now fully resolved.
Can I ask that you try to open your store again, and if experiencing an error, can you clear your cache and try once more.
Yet again I apologise for any inconvenience caused.
