Brian posted an update in the HBO forum about the status of the Mythica archive he created, which became the gold standard in Halo movie archives in a relatively short period due to its fantastic performance. He writes:

Whenever mythica does come back, there will be some changes. It'll have a lot less total capacity than before (30Mb/sec to start, down from 100Mb/sec), most importantly. There will also likely be a cap on how fast any one client can download from the server (something in the range of 1.5Mb/sec), and I'm not going to let single clients download several gigabytes in a day as has frequently happened in the past. None of this is final yet, but it should give an idea of what will happen.

The archive hasn't returned yet because the server itself hasn't yet come back from the last hosting facility, which went out of business.

In the meantime, Rampancy is willing to offer some of its capacity (admittedly, at best only 10% of Mythica's capacity at its peak) for hosting movies that have become difficult to find. Some we may already have. So if there's a movie you're looking for, but having trouble downloading, post in our Wanted Movies thread, or send me an email.
