Is Zalo down right now?
Check if zalo.me is down for everyone or just you
Zalo is up
All four probe methods (HTTP/1.1, HTTP/2, browser User-Agent, and curl HEAD) reached the server. If you can't reach it, the issue is local, try flushing DNS, switching networks, or disabling a VPN.
Get told if Zalo goes down
We're already probing Zalo every 5 minutes with four independent methods. Leave an email and we'll write the next time it goes down, and again when it recovers. No account needed.
We only mail you when Zalo actually changes state — no digests, no newsletter. You'll get a confirmation link first — we never mail an address that hasn't confirmed. How we handle your email.

Methodology
- Probe
- We send a GET request to the target URL with each probe method and time the full response.
- Counts as DOWN
- Every probe method fails the request (connect refused, DNS error, timeout, or HTTP 5xx).
- Counts as DEGRADED
- At least one probe method succeeds but at least one fails, the site is up but blocking or mishandling a specific request type.
- Detail
- Per-method results include HTTP status code, response time, and best-effort DNS / connect / TLS / first-byte phase timings when the Node HTTP client exposes them.
- Cadence
- Every 5 minutes, in parallel across 4 independent probe methods (HTTP/1.1 with strict TLS, HTTP/2, a browser User-Agent GET, and a curl-style HEAD) from our edge network. We check probe diversity, not geography — if a site blocks a non-browser User-Agent or only speaks HTTP/1.1, the four cards show it.
- Rate-limited targets
- If a host returns 429 or consistently drops connections from our IPs, we cap retries at 3 and report the last observed status, we do not flood the target to confirm the outage.
- Data source
- Our verdict is based on direct multi-method probes, every result above is a live network request, never a Twitter mention or DownDetector aggregate. User reports, when shown, appear separately below as a supplementary signal and are never used to determine the up/down verdict.

Common questions
Is Zalo down right now?
Our most recent probe of zalo.me returned "up" at 2026-08-12 05:46 UTC. Over the last 1 day we have measurements for, Zalo answered 100% of our probes, typically in about 1909ms, with no incidents recorded in that window. Every figure on this page comes from our own HTTP requests to zalo.me — four independent probe methods (HTTP/1.1, HTTP/2, a browser User-Agent GET and a curl-style HEAD) — not from user reports or a third-party feed.
Is Zalo down or is it just me?
If all four probe methods above show a response, Zalo is reachable from our network and the problem is local to you: flush your DNS cache, switch networks, disable a VPN, or try another browser. If two or more methods failed, the problem is on Zalo's side. When every method fails at the connection level we say "unreachable" rather than "down for everyone" — some large sites block monitoring networks at the edge while serving browsers normally, and we would rather be precise than dramatic.
How reliable has Zalo been recently?
Over the last 1 day we have measurements for, Zalo answered 100% of our probes, typically in about 1909ms, with no incidents recorded in that window. The 30-day strip shows one bar per day, so a single bad afternoon stays visible instead of being averaged away.
