According to Cloudflare, July 26, there was a lack of performance network in Greece, and more specifically in Athens.
Cloudflare has detected a problem with one Internet Exchange (IX) in Athens and disable using it until the issue is resolved.
With a view to a more immediate solution, the company abolished it traffic from Internet Exchange (IX), with an improvement being observed, and after some tests were completed, it was announced that it was definitively eliminated.
Network failure started from July 24 and was originally a global phenomenon affecting some Cloudflare IP, including in Greece.
This particular issue is probably related to a connection weakness observed in network of Cosmote the last 24 hour. According to user publications from social media, especially on Twitter, there is a serious delay in the Cosmote network.
The issue is still under way. Stay tuned for what's new.
