What's the alternative? It's not like we're some web property with an application, it's an ISP, and we sell internet services, and we've been around long enough that we still offer traditional ISP services (many for free) such as email, hosting, VPN service, etc, as well as telecom services. These often need to communicate with each other in some way, as well as many back-end services we've written to serve our staff.
Microservices come with problems, but honestly I can't see a large monolithic app (or even a few of them) being much better development wise, even if it might have been easier to test and set up a development environment.
