Very slow codepush downloads in UAE resulting in UNKNOWN_ERROR

[kyle-ssg]

Thanks so much for filing an issue or feature request! Please fill out the following (wherever relevant):

Steps to Reproduce

1. Attempt to download (9mb) https://codepush.blob.core.windows.net/storagev2/ID

Expected Behavior

Downloads in a reasonable time

Actual Behavior

Takes 3-4 minutes on a 250mb line (in app it times out)

This is making CodePush unusable for people within this region.

I think could be a a general issue with Azure Blob storage, not sure where to raise though.

Experiencing slow updates everywhere. I am considering only running check updates once a week per user to avoid this. Would much prefer a proper solution than this hack, but haven't been able to find a solution to the slow updates and it really impacts the user's experience to wait 3-20 seconds each time they open their app.

Today I release the update, and experiencing very slow updates/or no updates at all, I tried debugging most of the times it says Network request failed even with the perfect internet

[CodePush] Network request failed

Also we can see on our network monitoring most of the request are failing with appcenter

In fairness, I've seen updates take <2 seconds in UK. But UAE is definitely very very slow - in our case, we had to fork / increase the download timeout of 60 seconds. From my understanding it's an issue with azure where the bundles are stored, we found that UAE took a couple minutes to download a PDF vs 1 second in UK.

Also it became clear that we needed to implement a progress handler (in fact thats how we diagnosed the download speed was so slow).

With an additional fork of react-native-bootsplash we were able to also get around the horrible slow blank screen when it's installing the downloaded update.

function CodePushStatusDidChange(syncStatus) {
  switch (syncStatus) {
    default:
    case codePush.SyncStatus.DOWNLOADING_PACKAGE:
      updating = true
      rootPush(RouteUrls.AppUpdatingScreen, {}, 'AppUpdating')
      break
    case codePush.SyncStatus.INSTALLING_UPDATE:
      RNBootSplash.show()
      break
    case codePush.SyncStatus.UNKNOWN_ERROR:
      rootPop()
  }
}

function CodepushProgressUpdate: DownloadProgressCallback = (val) => {
    setCodepushProgress({
      percent: parseInt(
        `${((val.receivedBytes || 0) / (val.totalBytes || 1)) * 100}`,
      ),
      ...val,
    })
  }

Result:
