Answer
Home internet can go out not only because of a provider-wide outage but also for a simple physical reason: in one household, a gardener cut the internet cable, leaving the residents unable to work.
Such situations are especially critical for remote work because everything can look like a normal network outage. In fact, the problem may be near the house: a damaged cable, work in the yard, access to the utility panel, or a poorly protected line.
Therefore, when renting, it is important to understand where the cable runs, who is responsible for maintaining the property, and whom to contact in the event of a break. For work calls and urgent tasks, it is worth having a mobile backup so that one damaged wire does not bring the whole day to a halt or disrupt work.
