How to Fix AWS ME-CENTRAL-1 Outage & S3 Cross-Region Copy Issues

Select Language:

If you’re dealing with an outage in the ME-CENTRAL-1 region and need to move data between regions, here are some practical tips to help you manage the process smoothly.

First, for copying your data, consider using the “copy” command with the –recursive option instead of the sync command. This method can sometimes be more reliable during service interruptions. You can run a command like this:

aws s3 cp s3://source-bucket/ s3://target-bucket/ –recursive –source-region me-central-1 –region ap-south-1

If you have large files, using S3 Transfer Acceleration might help speed up your uploads. This feature routes your data through AWS’s optimized network paths, but keep in mind it might not be fully available during regional events.

To reduce the chance of retries failing, try copying smaller sets of data at a time. Instead of moving entire buckets all at once, focus on specific folders or date ranges. This makes it easier to manage retries if something goes wrong.

It’s worth mentioning that S3 Batch Operations are good for large data transfers in normal conditions because they work asynchronously in the background. However, during a regional outage, they will probably face the same issues as CLI commands since both rely on the source region’s health.

AWS S3 is built to be extremely durable—11 nines of durability. Data stored before an outage is backed up across multiple facilities in the region, making permanent loss very unlikely. Still, I can’t promise that your specific data would never be affected during a regional disruption.

Here are some additional tips to help during this process:
– Keep detailed logs of any failed transfers, and only retry those specific objects.
– If your command-line tools allow, increase timeout settings to give operations more time to complete.
– Run copies for different parts of your data in parallel. This can maximize your transfer speed during available windows.
– After copying, verify that your files are correctly transferred and intact.

Since you’re on Basic Support and dealing with a production impact, you might want to consider upgrading to at least Developer Support. This can give you access to technical assistance that’s more tailored to your urgent needs during this outage.
