Measuring packet loss and Latency Between eastern Europe and north america

Fri Mar 27 23:54:57 UTC 2020

I have a customer in eastern Europe accessing a SAAS application hosted in
one of Azure's north America datacenters. for the past few days every
morning between 3am and 6am est performance slows to crawl. This is person
is like 8am to 11am locally so they cant get much done.

The local ISP is providing 100mbps up/down.

So far speed test to Saas providers speed test page is slow 0.02mbps down 6
mbps up

Speedtest.net to north American ISPs like Verizon in New York slow

Speedtest to servers in Easter europe 100 up 100 down

Traceroutes/MTR dont help because a lot of hops seem to drop icmp packets

Need a tool or service that can detect packet loss/latency between provider
in eastern europe and a north american service provider. Any help is
appreciated
