Hopefully this isn't true any more,
I'd consider anything that has both of its something in such proximity as a sitting duck.
Over here, the commercial structure of FTTH and similar (we don't do any FTTC to speak of, and DSL is mostly being phased out for fibre, but it is dealt with similarly in what follows.) is that we've got a number of fibre communication operators that own the plant and light it up. They then let people choose their ISP on top via some portal thingy. For smaller, regional operators the ISP's sometimes meet them locally, and do handover, but for a number of the bigger fiber providers, that are present all over the country, they aggregate their handover a bit more, especially for smaller ISP's... One such handover facility was originally intended more as a passive fibre cross-connect site, and the rentable racks there were not dimensioned for anything power-hungry. Which people ignored and if they ran out of power in one rack, they bought another and strung an extension over.
Anyway, the telecoms regulator has rules in place, such that if your stuff is important stuff for more than a few people, you have to have redundancy for anything central, like interconnects. Which people ignored. Because such things are expensive and complicated. Tears into the revenue, it does.
Then the fibre company responsible for the cross-connect site had to perform planned work in the power plant. Which they did, and messed up. As people sometimes do. You can imagine the rest, a lot of residential stuff went dark.
Took no more than one hour to get things up again, but it woke people up properly and Words were had. Wonder if it helps.
