If you can't do your job without a tool, then you need to have a plan B on hand for when that tool fails. Both in the micro sense of the tools you use to code (editor, browser, laptop, mouse, coffee mug, etc) and in the macro sense of tools your organization uses (ticketing systems, chat, bathrooms). Show some initiative, figure out some mirrors for your dependencies, and try standing up a local caching proxy for your team. It'll probably take a lot less time than you think.
