In 2020 CenturyLink suffered an even larger outage that not only knocked out CenturyLink customers but spread into other networks, including Amazon, Cloudflare, and Hulu. The problem was blamed on a software update that blocked the establishment of Border Gateway Protocol (BGP) sessions and impeded broadband traffic routing.
T-Mobile also had a major network outage in 2020 that knocked out broadband customers and also cut off some voice calls and most texting for nearly a whole day. T-Mobile blamed the issue on problems with a leased circuit that was compounded by two previously undetected flaws in third-party software. Reports at the time said that the electronics failed on a leased circuit, and then the backup circuit also failed. This then caused a cascade that brought down a large part of the T-Mobile network.
In 2019 CenturyLink had perhaps the largest outage that knocked out much of its network and customers that relied on the Level 3 network for transport. The company blamed the outage on a bad circuit card in Denver that somehow cascaded to bring down a large swath of fiber networks in the West, including numerous 911 centers.
The FCC investigates big outages from time to time and opened an inquiry in October 2020 in a few of the outages listed above. The FCC also recently adopted a Notice of Proposed Rulemaking to investigate the disaster resiliency plans of major telecom providers to take a harder look at how cellular and broadband carriers make repairs after big storms.
Interestingly, the FCC recently fined T-Mobile $19.5 million for the 2020 outage, but not the other carriers. This is not because T-Mobile’s outage was worse than the others. T-Mobile was fined because they are a cellular carrier and still fully regulated by the FCC. But Comcast and CenturyLink are ISPs and under different regulatory rules.
Oddly, the FCC has very little power to do anything about ISP network outages because the FCC has very little regulatory authority over ISPs in general. The FCC abrogated its authority to regulate ISPs when it killed Title II regulation and handed a few vestiges of regulation to the Federal Trade Commission. The FCC only regulates ISPs tangentially through the specific authority given directly by Congress. Any authority the FCC once had as a result of claiming Title II regulatory authority is gone.
The process has finally started to seat a fifth FCC Commissioner, and the industry speculates that one of the early acts with five Commissioners will be to reinstate Title II authority. This effort might be a little more streamlined in the past because federal courts have already ruled that the FCC can choose to regulate or not regulate broadband.
Unfortunately, any move to regulate ISPs and broadband will only last until we have another shift in administration that wants to kill regulation again. We have ended up in an absurd regulatory merry-go-round where regulating or not regulating ISPs depends on the party that controls the White House. It makes no sense to not regulate ISPs at a time when cable companies have nearly total monopoly power in some markets. Overall, broadband might be the most important industry in the country because it powers just about everything else. Local jurisdictions around the country regulate occupations like nail salon technicians, plumbers, and masseuses, and yet we can’t get our act together as a country to regulate an industry where a handful of giant ISPs openly manifest monopoly behavior.
There is a really simple fix for this. Congress could give authority to the FCC to regulate broadband so that future FCCs or administrations could not undo it. It would only take a simple law that says something like, “The FCC shall regulate the broadband industry for the benefit of the citizens of the United States.” Obviously, lawyers could word this to be more ironclad – but giving the FCC the authority to regulate broadband doesn’t have to be complicated.
