I have tried to visit the official Ubuntu website, but it seems to fail with 503. Can anyone share any information they might know about this issue?

Can anyone share any information they might know about this issue?
We are just users. Anyone that could probably is not a member of AU and hopefully dealing with whatever the issue is.
This post is made with my Ask Ubuntu moderator hat on and my CISSP certified security professional hat on
According to the Canonical Services Status Tracker (https://status.canonical.com), acknowledgements were made about different infrastructure components being down starting around 12:30PM UTC-04:00 on 2026-04-30.
Throughout the day, the infrastructure has indeed been down. The exact cause is not officially identified by Canonical at the time of this post.
However, according to VECERT, at approximately 3:03PM UTC-04:00 on 2026-04-23 a DDoS attack was active against Ubuntu infrastructure. A screenshot of the post from X/Twitter is below:
Nobody at Canonical has replied about this even with me prodding with my Ubuntu Community Council hat on, so it's likely they are actively trying to address this issue.
As of 00:42 UTC-04:00 on 2026-05-01, much if not all of the infrastructure continues to be down, and we should consider this an "active incident" that will develop further in the next day or two.
