While this sounds rather ironic, you can view the collection of the complaints when you search for “Maxis Twitter” through Twitter itself:

Some users pointed out that changing to an alternative DNS address would solve their issue. For some, they managed to connect back to Twitter by restarting their router but there were also other users who still not able to access the social media network after trying these methods and was forced to either utilize VPN or connect to mobile providers to get back on Twitter. Through these tweets, some customers also revealed that they can’t access other websites such as Maybank2u and Shopee through Maxis Fibre too: https://twitter.com/nymzysn/status/1252901471240118274 https://twitter.com/1Obefiend/status/1252836408319864833 We have reached to Maxis regarding this but so far, the company has nothing to update at this moment. However, one of the responses by the telco’s customer service on Twitter did revealed that Maxis is already aware of the issue with Twitter.
