Hi @Cesar Tovar
I’m sorry to hear about the unexpected increase in your bandwidth billing. You mentioned you checked your logs, did you notice if both web apps had a spikes in usage at the same time as increase in billing?

I would also suggest checking your bandwidth usage details. Azure provides detailed bandwidth pricing information. You can see if there’s been an increase in data transferred out of Azure data centers, or data moving between Azure data centers

Also, keep in mind Microsoft Azure made some changes to its bandwidth billing model in September 2020. The changes included moving to a source-destination billing model and dividing metering into inter-region meter IDs. You might want to check if these changes have affected your billing.

Best, Grace
