Elon Musk promised to fix Twitter's slowness in many countries and apologized for the inconvenience. MIT Technology Review said that a Twitter breakdown would gradually reveal itself in little errors, some seen and others not noticed, that eventually build up to one big problem. An anonymous Twitter engineer offered a scenario of how Twitter will go down: "Things will be broken more often. Things will be broken for longer periods of time. Everything will compound until, eventually, it's not usable." In response to Elon Musk's claims that Twitter is slow due to RPCs, former Twitter Senior Infrastructure Engineer Sam Pullara has stated that the problem lies not with the RPCs, but rather with the backend of the service. He has also refute the idea that RPCs are to blame for the slow service outside of the USA, explaining that all countries share the same RPCs. Musk had previously tweeted that he had ordered the removal of what he felt was superfluous code from Twitter's codebase. Zoë Schiffer, the managing editor of Platformer, tweeted that Twitter is locking down their code base. According to an internal email, Twitter employees that Schiffer has spoken to are unsure of what is happening. Security specialist and noted computer security expert Ian Coldwater tweeted their concern about Twitter, saying that people should back up their data and social graphs immediately. Silicon Valley tech entrepreneur Anil Dash tweeted in response, saying that Coldwater is "as credible a voice as you can find". Over the weekend, security expert Jane Manchun Wong downloaded her Twitter archive because she was concerned about what might happen to Twitter. Twitter's SMS messaging system was down, or the system for downloading archives was no longer working. Many people who were warning about an impending Twitter outage are highly credible people with deep knowledge of technology and even expertise with how Twitter works. If someone like Wong is worried about what's happening to Twitter, then it might be prudent to consider that Twitter's ability to stay online may be diminishing faster than is generally apparent.
